Srsly.

Code:

Once per turn, select 1 monster you control and give control of it to your opponent. When that monster is destroyed by battle, draw 1 card.

Add a card or two that gains advantage through battle such as:

Code:

Once per turn, you can reveal 1 "Candy" card in your hand to have this card gain 400 ATK, until the End Phase. If this card destroys an opponent's monster by battle, select 1 "Candy" Equip Spell Card from your Deck and equip it to this card.

And finally, something to give them that just keeps giving you advantage, like:

Code:

Doom Plant

When this card is destroyed by battle, add it to your hand during the End Phase.

Let's just see the advantage you can get, Destroyer on field, Doom Plant on field, HERE, HAVE THAT. on field or in hand.

Switch control of Plant (field advantage takes a -1). Destroy it by battle get a +1. HERE, HAVE THAT. kicks in to give you a draw (+2 to hand advantage), and get Doom Plant back in your hand at the End Phase for a tasty +3. Rinse and repeat.

HERE, HAVE THAT.
