Most top deck dont run 3 mirror wall anyway stop crying lol. There are tons of counters ( twister trap jammer tornado etc) and honestly once you get good at pvp you just know when its there. Its a caed in the game gets used to it and get yourself one :) Depending on deck 1or 2 is all u need
Twister can counter mirror only if the mirror's user is a complete 🔥 and activates it in the battle phase and not in the damage step, so stop saying that Twister is a counter. The only "direct" counter is Trap Jammer, which isn't used that often.
Dude not gunna have a stupid argument here but mirrorwall is very obvious... you have 2 mosters on the field you ram one in and then twister it... Its really not that big of a deal
Just from leveling and stage mission you are given 22000 gems.. That enought to guarantee 2 mirror walls with the worst possible luck... Paying is not a necessity!
