I mean Cyberdark Impact. The whole Senet Switch, Blasting fuse, Alien infiltrator... those whole ilk of cards.
Link monsters are cool, they add this whole mechanic of zone presence. People can now start playing monsters into specific zones if they think their opponent has a card that uses that zone already, which adds player interaction. Suddenly ojamas get a buff, for controlling the zones your opponent can and can't use.
It has potential, sure, but the fact that they've completely nerfed everything that existed before to get to it is... wow. It's impressive, i'll give them that. Subterrors, Kozmo, Yosenju, Monarchs, and Kaijus are the new meta now.
