If this has not been done yet, I personally devised a deck that works with Pendulum monsters and Gemini monsters. So you know how a Gemini monster that is summoned to the field is like a monster in Magic the Gathering that has summoning sickness, in that it cannot use its effect(s) immediately? Well to bypass that would be to special summon it of course. Now since a pendulum summon is considerably a special summon, once you pendulum summon a Gemini monster you can normal summon the Gemini monster immediately so as it may use its effect.
If this did not blow your mind, consider it blown!
