I had this trinket with the one that buffs the shop after you take damage 4x. Urzul went hard, ended up at 10k atk/11k hp. You don't have to think with this comp. As Jeef said, "Play demon, buy spell, repeat." At a certain threshold optimizing just losses you stats.
Watching him pop off like this makes me want to play bgs but I never do as well, so I just watch more videos and try again. An endless that I never mind
Is it a bag ? At 23:15 he bought a demon with money from a trinket and after that when he had a demon that make one demon for free, for some reason that demon worked twice, and he bought two demons for free
random though.. but maybe a mechanic like if turn count is more than 8 transform this minion into X.. over that humming bird this idea came to mind.. there was a cool thing with mana saber's summons having 0 atk that made a com good, idk which or what. if this humming bird back then was in pool.. and they also made it so in early game it gives +1 atk to your beasts.. but in mid to late game turn into another version of itself that give +1 atk to all beasts, enemies included.. for early game you wont be punished and for mid and late game this minion might be come scam unit
