As Stenn enters, choose a card type other than creature or land.
Spells you cast of the chosen type cost less to cast.
: Exile Stenn. Return it to the battlefield under its owner's control at the beginning of the next end step.
Stenn picks a non-creature, non-land card type (usually instant, sorcery, or enchantment) and shaves off every spell of that type, letting you chain a low-curve UW control or spellslinger deck and snowball card advantage. You blink Stenn with its own ability to re-choose the type as the game shifts. Win by leveraging cheap interaction, card draw, and a token/enchantment engine to grind opponents out.
Built-in cost reduction accelerates the entire deck and stacks with other reducers
Two mana, easy to recast, and self-protecting via the exile/return ability
Flexible: re-blink to change the chosen type for the current game state
UW gives access to the best counters, removal, and card-draw enchantments
Reduction only applies to one chosen type, so multi-type decks waste value
Stenn does nothing offensively and provides no evasion or board presence
No inherent win condition—needs the 99 to actually close games
Vulnerable to fast aggro and combo since reduction is incremental, not explosive
