Combo is like Undatakah to go infinite (immortal prelate deathrattle).

You can give it Lifesteal (with the twinspell thingy), it takes the AOE effects from the deathrattles, and you can give it taunt with the new 6 mana spell. You have Banker to get an extra one (to be safer). You basically never fatigue and keep healing yourself with lifesteal AOEs. Pretty memey

This is the idea, maybe it'd be useful to play 2x of some cards to be safe against on polymorph-type of cards. Ofc if you put 2x Prelates (like i'd do) you never want to play both if the opponent kills the first
Just play 2x banker 4HEad
