Few decks ever suceed without creatures. Only the stoutest of control decks can surivive without them, and even then, most control strategies unleash a few monsters to finish the job. However, not any creature will do. Many are printed, few are chosen. Gone are the days of Grizzly Bears and Shivan Dragon; in today’s removal heavy world, every creature must be worth more than it’s mana cost, or at least the cost of the spell used to take it out.
So who are these superstars of today’s standard metagame? It’s hard to tell. A few stand out, either being great on their own or finding a home in a currently sucessful deck.

Like any good superstar; just as many people hate the Baneslayer as love her.
Here are the critters I consider A-listers. Most of them don’t need any explaination; you should already know what they do.
Baneslayer Angel
Bloodbraid Elf
Putrid Leech
Sprouting Thrinax
Ranger of Eos
Broodmate Dragon
Iona “I-own-you“, Shield of Emeria
Wall of Denial
Lotus Cobra
Sphinx of Jwar Isle
However, with Zendikar on the table for little over a month, decks are still being tuned in card shops, apartments and basements, and new creatures are being used and abused, just waiting to be unleased on an unsuspecting meta.
Here are some of the guys I think might be up-and-coming stars.
Knight of the Reliquary
I mentioned this before, but I think KotR is going to only become more powerful as the Zendikar block continues. She works great with the fetches and with the introduction of the landfall mechanic, can do all sorts of little tricks by sacking lands and putting another in play. She can grow quite large too, sacking lands to find fetches to sack for another land.
Steppe Lynx
Steppe Lynx has two things going for him, his mana cost and the ease of triggering the landfall mechanic. In the right deck he could dish out some serious early damage, as well as be a nice surprise blocker. The lynx can also be found with Ranger of Eos, allowing for players to consistantly put him on the board. The one W cost also makes him a very efficient; no matter how they get rid of him, you only paid one. If the right landfall deck is built, this guy will be a superstar.
Scute Mob
A lot of people are on the fence about this guy, but I think the bug is one of the most efficient creatures around. The mob is a 1/1 for G, but eventually he’s going to be a 5/5 for G, and then a 9/9 for G. However, the “eventually” part is what scares most people off. What also scares people is wasting removal, any removal, on a 1/1 you paid G for, and they’ll let him nibble away until they absolutly have to do something about him. If he gets his grow on, he becomes a beast. I think the mob has a place in a lot of deck, from aggro to control, and making him grow isn’t hard, especially with a little mana acceleration.
Ob Nixilis
Like the Lynx, with a deck centered on landfall, Ob could become a serious threat. Yes, there is a chance you are going to pay 3BB for a 3/3 who is going to get smoked by Lightning Bolt, but if you are smart about it, there is also a chance you are going to get a 6/6 or a 9/9 and make the opponent lose 6 life for 5BB. People are tyring to make this happen as we speak.
ThornlingWhen people first saw Thornling, they went nuts; until they saw Path to Exile, that is. However, last time I looked, the most popular deck in the format doesn’t run white, or anything that could deal with him at all, for that matter. Thornling is a solid creature that would have been better in a format without so many “removed from game” effects, but that shouldn’t mean he never sees play. Perhaps he could be a good sideboard card against Jund, or as a nice ramp monster. Remember, they can’t path him unless they have the card in their hand. Don’t be a fraidy-cat!

Dumb looking and a bit redundant, but he could be a solid beater.
Great Sable Stag
The stag saw a lot of play when Faeries was still in standard, but since then, players have put him down for different monsters. I wonder, why? He still has protection from black, and black is all the rage right now. Yes, the Jund player can bolt him, but that is four cards in 60, and Vampires can’t do shit. The proud stag should at least be boarded if players don’t want to run him in the maindeck.
Bloodghast
Bloodghast has a few things keeping him from greatness right now, Vampires, Creatures, and spells that have the word “exile” on them. All are very popular, and all pose a major threat to the ghast. He doesn’t have a home outside vampires at the moment, and that deck is pretty bad, at least when it runs up against competent players with a good deck. The Bloodghast is also terrible when it comes to fighting the other super-powered creatures in today’s metagame, though he can do a fair job of trading with a few of them. Finally, he gets pathed a whole lot, which wouldn’t be so much of a problem if most decks running path didn’t also run creatures he can’t get through. However, if he finds his way into a non-vampire deck or if the metagame sees a shift from it’s current state, he could become a nusiance. He is nearly impossible to deal with using conventional removal, and countering him is just as useless. All it takes is a few in the graveyard and a land drop to cause a serious problem.
Emeria Angel
Again, if landfall becomes a serious deck, this critter could become quite popular. A 3/3 flier who makes little birds every time a land drops. It wouldn’t be hard to power out 2-4 birds in a turn, and this could be deadly with Garruk and Overrun.
Please notice, landfall looks to work the best with W/B and G at the moment, which also happen to be the colors with some of the best spells avaliable at the moment.
World Queller
The queller is a nice combination of body and utility. He is a 4/4 for 5, which isn’t bad when you couple it with the ability to cause each player to sacrifice a permanant of the type you choose each upkeep. You get to choose the type, each upkeep. It might seem awkward at first, but with the right set-up, the savvy player can find ways around his drawback of having to sacrifice something of your own.
There are the guys I would be watching. To see some new standard decks and perhaps a glimps of how these creatures might be put into a deck, visit the official WotC website to see the recent Magic Game Day decks.
