Still, it is pointless to play 3 cyber twin. You{ll never get to play a 3rd. Chimeratect may not come often but it is still a solid option for those cases where you need it.
ok, you must all be dumb, chimeratech gains 800 for each machine fusion material, and it can attack monsters equal to the number of fusion materials, its not it can only attack 1, its all monsters, so, if opponent controls 3, and you ue 5 materials, you can attack 5 times on the 3 monsters but not directly,
3 Cyber twin is excessive, but it's pointless to use Chimeratech without cybernetic fusion support as you'll never summon one bigger than End. It's a pretty dated card, its inability to attack directly, those multiple attacks go to waste and it's better to just use twin.
Still, I think it’s useful just have in the extra deck in case you need multiple attacks to win over monsters that can’t be destroyed by battle potentially (Amazoness and Neos Fusion comes to mind)
