Bristly Bill, Spine Sower

Trample When this creature enters, you gain 3 life. Plot 3G (You may pay 3G and exile this card from your hand. Cast it as a sorcery on a later turn without paying its mana cost. Plot only as a sorcery.)

Spree (Choose one or more additional costs.) + 1 — Search your library for a card, put it into your graveyard, then shuffle. + 2 — Return up to two creature cards with total mana value 4 or less from your graveyard to the battlefield.

Steer Clear deals 2 damage to target attacking or blocking creature. Steer Clear deals 4 damage to that creature instead if you controlled a Mount as you cast this spell.

At the beginning of combat on your turn, put a +1/+1 counter on target creature. Whenever this creature attacks while saddled, double the number of +1/+1 counters on target creature. Saddle 2 (Tap any number of other creatures you control with total power 2 or more: This Mount becomes saddled until end of turn. Saddle only as a sorcery.)

Whenever you commit a crime, put a +1/+1 counter on Lazav. Then you may exile a card from a graveyard. If a creature card was exiled this way, you may have Lazav become a copy of that card until end of turn. This ability triggers only once each turn. (Targeting opponents, anything they control, and/or cards in their graveyards is a crime.)

Flying Plot 3U (You may pay 3U and exile this card from your hand. Cast it as a sorcery on a later turn without paying its mana cost. Plot only as a sorcery.)

When this creature enters, target instant or sorcery card in your graveyard gains flashback until end of turn. The flashback cost is equal to its mana cost. (You may cast that card from your graveyard for its flashback cost. Then exile it.) Plot 2U (You may pay 2U and exile this card from your hand. Cast it as a sorcery on a later turn without paying its mana cost. Plot only as a sorcery.)

Spree (Choose one or more additional costs.) + 3 — Create a 2/2 white Spirit creature token with flying. + 1 — Counter target spell unless its controller pays 2.
