skull shield + aflatoxin, a bunch of control and finally bone wall + dry spell/bone yard (i think boneyard might be overkill, probably better to run more aflas or other control over this).
purify deals with poison and momentum
skull shield can kill immortal creatures, but this is probably the hardest mechanic to stop when momentum is added to them
ice bolt deals with early devourers and can help slow down things like pulverizer/morning glory
30 turns later you win while your opponent rages on chat. would love someone good to test against!
on an interesting note, the probability of skull shield triggering is based on the creatures current HP compared to max HP. So ice bolting a big dragon will increase its chances of dying to skull shield, and can freeze as well
heres a picture without the lands. easier to see and im still figuring out the best land base:
