Bant Snakecharmer

When Bant Snakecharmer enters the battlefield, create two 1/1 blue Snake creature tokens with deathtouch.
Retreat {1}{g}{w}{u}( When this creature deals combat damage, you may pay {1}{g}{w}{u}. If you do, return this creature to its owners hand.)
When a Snake creature token you control dies, if it wasn't dealt damage, put a +1/+1 counter on target creature.
