Too many multiplication actions crashes game
The game will crash currently when it has to multiply too large of numbers together. Prior to crashing it will lag intensely, which is frustrating both for myself and my opponent - this has caused me to abandon decks I spent a ton of wildcards on because they're just too liable to cause a crash.
I've had this happen on my B/W Legendaries deck I made, where Ratadrabik, Mondrak and Drivnod are in it to cause huge piles of legendary copies, as well as a deck a few rotations back that was Landfall based, when too many Scute Swarms would spawn. I've also had it crash with a deck I made using Mystic Reflection, Calamity Bearer and mass token spawners - create ~20 copies of Calamity Bearer, attack - then lag out as the game tries to multiply the damage of each by 2^20th.
I don't totally care if my numbers cap - if my Calamity Bearers hit for 999 instead of like 3 million. If my tokens cap at 256 but it doesn't actually cause lag, fine. But the game crashing because I tried to be creative building a deck sucks - especially as someone that really enjoys cloning and token armies.
