Sonic, Starfall Explorer

First Strike, Haste.

Whenever Sonic enters or attacks you get an experience counter then reveal X cards from the top of target player's library where X is the amount of experience counters you have, You may Exile an instant or sorcery spell from among them and encode it onto sonic as though it had Cipher, if not, put a +1/+1 counter on sonic and draw a card, put
the other revealed cards onto the bottom of that players library in a random order.
