Great Train Heist

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.

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.)

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.)

Scorching Shot deals 5 damage to target creature.

Look at the top three cards of your library. You may exile a nonland card from among them. If you do, it becomes plotted. Put the rest into your hand. (You may cast it as a sorcery on a later turn without paying its mana cost.)

Return up to one target creature card from your graveyard to the battlefield. Return up to one target permanent card from your graveyard to your hand.

This land enters tapped unless you control two or fewer other lands. T: Add U or R.
