Captain America, First Avenger

First strike, vigilance
When Captain America, First Avenger enters
the battlefield, if it was kicked, put a shield
counter on target creature you control.
Whenever Captain America attacks, look at the
top X cards of your library, where X is Assemble.
You may reveal a creature card from among them
and put it into your hand. Put the rest on the
bottom of your library in a random order.
