Draw a card.

Shield Sphere

Defender
Whenever this creature blocks, put a -0/-1 counter on it.

Aether Gust

Choose target spell or permanent that's red or green. Its owner puts it on their choice of the top or bottom of their library.

Pit Trap

{2}, {T}, Sacrifice this artifact: Destroy target attacking creature without flying. It can't be regenerated.

Reckless Handling

Search your library for an artifact card, reveal it, put it into your hand, shuffle, then discard a card at random. If an artifact card was discarded this way, Reckless Handling deals 2 damage to each opponent.

Shuriken

Equipped creature has "{T}, Unattach Shuriken: Shuriken deals 2 damage to target creature. That creature's controller gains control of Shuriken unless it was unattached from a Ninja."

Island

Battering Ram

At the beginning of combat on your turn, this creature gains banding until end of combat. (Any creatures with banding, and up to one without, can attack in a band. Bands are blocked as a group. If any creatures with banding you control are being blocked by a creature, you divide that creature's combat damage, not its controller, among any of the creatures it's blocking.)
Whenever this creature becomes blocked by a Wall, destroy that Wall at end of combat.
