"Bubonic Vermin" allows you to take 2 extra monsters directly from your deck, it could be for defense and also to tribute another monster, if you FLIP its effect, you can have 2 monsters to tribute summon another of any kind.
"Chimera the Flying Mythical Beast" is a classic card but it is difficult to make it work. "Berfomet"’s effect can help you getting both monsters for fusion, but it need to be tribute and flip summoned.
"Bazoo the Soul-Eater" seems the strongest here, since its attack points can go very high by its effect.
