Changeling
Whenever you cast an instant or sorcery spell, if it targets one or more other permanents you control, create a token that's a copy of one of those permanents.
When a spell or ability an opponent controls causes you to discard this card, create a token that's a copy of target permanent.
Orvar churns out token copies of your best permanents every time you cast a cheap instant or sorcery that targets them, snowballing into overwhelming value or a combo finish. You spend the early game ramping and protecting Orvar, then chain cantrips, bounce spells, and protection spells that incidentally target your own creatures, lands, or artifacts. Each copy compounds your board, mana, and engines until you bury opponents or assemble an infinite loop.
Add fast mana (Mana Crypt, Mana Vault, Sol Ring) and untappers (Dramatic Reversal, Isochron Scepter) to enable infinite-mana combos that close games quickly. Layer in strong protection (Heroic Intervention via blue's Veil of Summer alternatives, plus counterspells like Swan Song and Pact of Negation) so Orvar survives, and include tutors like Mystical Tutor and Personal Tutor to find your engine pieces. Tighten the curve toward free and one-mana cantrips so every turn produces multiple Orvar triggers.
