Is 1085 defense enough?
Achieved this by having a throwing axe from Tanx (first card you play each combat is played an extra time) and combining it with the sealed throne (whenever you play a card, gain a blue star)
So essentially i was getting 2 stars for playing any card
finally, particle wall costs 0 mana and 2 blue stars, gives you 9 defense and returns to your hand.
So essentially, for me its an infinite free card that gives me defense.
After 1085 i got tiered of stacking, but theoretically you can go infinite
And also theoretically, if you get a card that costs 0 mana and 1 star, you can infinitely stack blue stars that way. combine it with stardust and you get infinite damage.
its a shame the game trolled me a little bit and i had almost no star-related cards in my deck....
