I just finished a Prismatic Bridge EDH Deck with "Siege Rhino" as its only creature. THe whole deck is about protecting this creature and flickering it as many times as possible. My question is if there is any one creature that would be maybe a better alternative than siege rhino? with an strong etb trigger that can be if flickered over and over again be the win condition.
Thanks for any Help
So, apparently once upon a time Siege Rhino was a house in Standard. However, that was (a) a long time ago and (b) this is Commander. This guy looks to do... very little, frankly. In the nicest possible way, I think the Rhino is a truly terrible choice for this. (And if you don't believe me, consider that all other things being equal you would need it to enter the battlefield fourteen times to kill everyone; unless you have some sort of cloning, Panharmonicon/Yarok, infinite-blink combo, whatever, that's way too slow)
If you're going to the effort of just having a single target in your deck for the Bridge, why a 4-mana dude with a mild ETB drain? Why not, say, Koma, or Sheoldred, Jin-Gitaxias, or Ugin? Also, since you have many very powerful options, most people are happy to put more than one in. You don't really want to be drawing these, probably, but if you're fortunate enough to get a second upkeep you may as well get a second bomb out. I think that if you are building this to get a specific creature it's because you need exactly that creature, which probably means it's part of some kind of combo win or, perhaps, is absolutely key to some crazy jank strategy. However you still have to get an upkeep with the Bridge, which most people are going to try to prevent, so it's still not the easiest thing in the world.
Yeah, if I were to only run one creature, I would play something that shuffles back in to the deck when it dies. My vote would either be for Serra Avatar or for Worldspine Wurm.
If going with Serra Avatar you can run enchantments like Angelic Chorus and Warstorm Surge to double your life total and deal that damage directly to opponents. You can also fling it with cards like fling, or deal the damage directly through cards like burning anger and soul's fire.
If going with the Worldspine Wurm I would just attack with the creature and sac it at the end step before your turn to get the 3 trampling tokens each turn. Than run cards like overwhelming stampede and triumph of the hordes to close out the game once you have a sufficient board state.
