Islandwalk (This creature can't be blocked as long as defending player controls an Island.)
Whenever Thada Adel deals combat damage to a player, search that player's library for an artifact card and exile it. Then that player shuffles. Until end of turn, you may play that card.
Thada Adel is a mono-blue tempo/value commander that connects in combat to steal artifacts directly off opponents' libraries. You curve out, protect a 2/2 evasive body, and grind incremental advantage by playing stolen mana rocks, mana fixers, and bombs—while leaning on islandwalk and counterspells to keep her swinging.
Islandwalk makes her nearly unblockable against blue-heavy tables
Steals opponents' best artifacts (rocks, equipment, bombs) for tempo and ramp
Cheap 3-mana commander you can recast easily
Mono-blue gives access to the best counterspells, card draw, and protection
Naturally fuels artifact synergies and storm/cost-reduction lines
Only a 2/2—dies to nearly any removal or chump-blocking with non-walked creatures
Islandwalk does nothing against opponents not running Islands
Effect whiffs entirely on players with no artifacts in library
Mono-blue lacks reliable creature removal and recursion
Relies on connecting in combat, making it fragile to fogs, tax, and Stax
