just started, got the add energy thing, and saw that it can go over three unlike six card hand limit. I don't feel like rerolling for god run but I think the way to do it would be to replace swords then shields with that stuff, then do stuff like [spend all mana]*3 energize, waste useless 1*1 shield, 3*2 card draw, ... loop without ever winning just to see if u can get super big numbers. I haven't played much but judging by screenshots on this page, seems u can also have effect strengthened by how many shields u have, which seems amazing as shields don't get spent until your turn is over
woah, multiply by shield is OP so I should've saved big spend for after. new setup. after initial spend3, energy ends up getting tripled. now get 9 shields, and with the remaining 6 energy, can get 6*9 at which point u can just go for the kill. 2*3 shields then 1*6(shields) card draw isn't all that good cuz the free draw at start of next turn is wasted
