I'm looking for cards that allow me to return one or more Monster Cards from my own side of the field to my hand repeatedly. By repeatedly, I mean that they can be used several times per turn, including with some workaround. An example of what cards fit my needs is Genex Ally Birdman, who returns one face-up Monster Card to Special Summon itself, then if I somehow get it back into my hand, I can use it again (and yes, I'm aware it banishes itself, there are still ways to get it back).
What I'm not looking for:
- Trap Cards. I need cards that work immediately.
- Cards that return any number of Monster Cards once. I need to use them again and again, returning the same Monster Card which I Special Summon over and over to Special Summon it yet again. Returning all at once doesn't help unless I can do it as often as I like.
- Cards that return a specific Monster Card. I need to return generic Monster Cards.
Also, Monsters that must be Normal Summoned are of limited use unless their effect can be used as often as I like. Swap Frog comes to mind, but he's more or less useless because he returns either himself or exactly one Monster and that's it.
For some context, and to make it easier to evaluate whether your idea fits the requirements, here's the intended in-game purpose of this: I want to re-use cards like Spell Striker, Black Luster Soldier - Envoy of the Beginning or Trap Eater in order to banish all Spells/Monsters from my GY/eat all the Traps.
