Orange Cassidy

When blockers are declared, if Orange Cassidy
is not attacking or blocking, you may pay {u}.
If you did, scry 2.
If it is attacking or blocking, you may pay
{u}, {r} or both. If you paid any of the costs,
reveal the top card of your library and draw it.
If you paid {u}, Orange Cassidy gets +0/+X
until end of turn, where is that card's cost.
If you paid {r}, Orange Cassidy gets +X/+0
until end of turn.
