You may look at the top card of your library any time.
You may cast Merfolk spells from the top of your library.
Whenever you cast a Merfolk spell, you may pay . If you do, create a 1/1 blue Merfolk creature token.
Emperor Mihail II is a mono-blue Merfolk tribal commander that turns your library into extra hand space and rewards you for chaining Merfolk spells. You flood the board with Merfolk while casting off the top, generating 1/1 tokens with each Merfolk cast, then leverage lords and unblockable enablers to swing for lethal. The deck plays as a fast, resilient go-wide tribal aggro/midrange shell.
Generates card advantage by casting Merfolk off the top of your library every turn
Each Merfolk cast can spawn a free token, snowballing your board with anthem effects
Mono-blue gives access to the best counterspells and protection to defend your board
Cheap commander (3 mana) that immediately advances the gameplan when recast
Deep, well-supported Merfolk tribe with multiple lords and unblockable payoffs
Mono-blue lacks efficient board wipe recovery and removal beyond bounce/counters
Vulnerable to sweepers since the strategy is heavily board-dependent
Token generation costs extra mana, which can be taxing in faster games
No built-in evasion or recursion on the commander itself
Topdeck-casting only helps if the top card is a Merfolk, so non-creature spells can clog it
