To what desired end?
Summon to enemy field. Attack its 0DEF/Probally 0ATK for big damage and summon the thing back to your own field. If you have a graveyard loaded with reptiles, then its big.
So, it's simply an Attack Position Mis Revive. There's got to be a use for that Levelgain, though.Calculator
Mis Revive brings back from enemy's grave.
