All "Ancient Gear" monsters gain 300 ATK. Each time a monster(s) is Normal Summoned/Set, place 1 counter on this card. If you Tribute Summon an "Ancient Gear" monster, you can substitute this card for a Tribute(s), if the number of counters is equal to or greater than the number of required Tribute(s).
PLEASE, for the love of christ, remove this damn card! You add gladiator beasts, and fail to add test tiger and gyzarus, but noooo, we'll add a 3000 atk (3300 with this card), stops all spells and traps during battle phase (effectively negating 80% of countering cards in the game), piercing damage. Like, go absolutely f*ck yourself! If this is allowed in game, it should be strictly allowed for pve and banned in PvP.
Hands down, I bet the top ranked players will have AG decks.
