On the lifegain i've thought about it. Trostani, selesnya's voice
is currently still helming Wurms but I do have a true conviction laying around.
On top deck maniuplation: Ive felt in my past games with mayael top doesnt do anything that mirri's doesnt and the cost just makes mayael even more expenive to activate.
Basalt is mostly in here to enable the turn 4 activation with mayael and they the infinite combo. I've considered thran and worn but im leaning to not adding them atm due to im looking at possibly adding a lot of artifact wipes if my meta keeps going rock based.
Xenagod is supposed to be on my list of things Im adding to the deck same with with surrak, the hunt caller
. Hasste is a huge issue in the deck and im even considering after those two considering anger
