Symbol of Unsummoning
The clearest window into what Portal was built to do: take Magic's most intimidating subsystems and strip them out, leaving interactions a newcomer could parse on sight. Here that means splitting two effects that blue normally fuses with conditions and timing tricks. One half is a tempo play (return a blocker or attacker to its owner's hand, undoing a turn of their development); the other is a card-flow play (refill your own hand so the bounce never costs you a card). Both resolve in plain sequence, with no keyword density to decode and no combat trick lurking behind the sorcery restriction. That legibility is the design's entire purpose: it lets a new player feel tempo and card advantage operating at once, in their simplest possible form. The "bounce plus a draw" pattern runs deep through blue's history, and few versions express it this nakedly: no upside hidden behind a clause, no drawback beyond the sorcery-speed limit that keeps it out of combat. Its identity is less about power than about what it documents. Wizards spent an entire product asking which core interactions were worth making obvious, and decided tempo-stapled-to-a-cantrip was one of the shapes worth setting in front of someone holding their first deck.
