Aaaaaahh, okay yeah that makes sense. Well, the one positive is unless a Jinzo he has on the field has Amplifier, he can't use it while his boss is out. Otherwise... Focus on a Horus/Silent deck with Spell support rather than too many traps
The strategy is to send REBD to the graveyard. I can understand your frustration, because it’s a very effective strategy. Might I suggest adding some banish as tech cards, they’re effective at stopping graveyard to field strategies.
Fusion summoning is like a square and a rectangle.
The square would be a special summon
The rectangle is fusion summoning
A square can be a rectangle but a rectangle can't be a square right? So a special summon could be a fusion summon but a fusion summon can't be a special summon.
