>>47104934Well, I could see it working as a gimmick for a few unique Pokemon like the Unova dragon:
>Dragon/Fire/Electric(No Ice because that is just suppose to be the leftovers)
Though a 4x weakness to ground would hurt, a 4x weakness sure as hell didn't stop Mega Fug, given that ability & all.
As an entire gimmick I don't see it lasting long. Game Freak already dumbs these games down for casuals so they sure as hell aren't about to complicate things to this extent. Just like how Poke fusion is limited to a few specific legends/gimmicks, this would be treated the same. More in favor of dual typed moves really.
