a lot of these cards seem pretty slow for edh, and the lifegain from cards like Shattered Angel is going to be so insignificant in edh. you should also be running Emeria, The Sky Ruin if yr gonna be playing mono-white. in fact, there are so many things that should be done to this deck that i don't know where to start exactly.
also i just think tokens is a very weird route to take with isamaru because he's typically a voltron general.
I would say most people run Isamaru as a voltron deck. Stuff like Kor Spiritdancer and the totem armors. Also lots of equipment. 33 might be too low on lands. If you stick with tokens, Odric or Mikaeus might make better commanders. You could even alternate commanders.
