Invasion of Ixalan // Belligerent Regisaur
The paradox at the heart of the Siege type: the front face pays you the instant it lands, but the back face only arrives if the opponent you assign to guard it lets it fall. That split is the whole design. The enters trigger digs five deep and banks a permanent to hand immediately, no combat required, so the selection value is locked in before anyone attacks. What has to survive is the flip, which happens only once a defender's damage threshold is finally pushed through by whoever kept swinging. Collect the far side and you get a trampling Dinosaur that converts each spell you cast into indestructibility until end of turn. That clause bites hardest on the turns it deletes a decision across the table: destruction-based removal aimed at the Regisaur simply whiffs the moment its controller casts anything, so a deck that keeps spells flowing after the flip holds the board rather than trading for it. The two halves read as separate cards because they behave like separate cards: one a front-loaded selection payout that hands you a permanent on arrival, the other a resilient beater gated behind combat pressure that punishes patience. Both faces make the same argument the entire Siege cycle is built to make, that a permanent worth attacking is a permanent worth building around.
