Whenever you cast a noncreature spell, if at least four mana was spent to cast it, tap target creature an opponent controls and put a stun counter on it. (If a permanent with a stun counter would become untapped, remove one from it instead.)
Whenever you cast a noncreature spell, if at least eight mana was spent to cast it, put eight +1/+1 counters on Ultros.
Ultros is a mono-blue spellslinger commander that rewards casting expensive noncreature spells: hit four mana spent for soft removal (tap + stun), and eight mana spent to grow Ultros into a 10/12 beater. You ramp into big X-spells, draw, and counters while locking down opposing creatures, then close with a buffed Ultros or a big finisher.
Add fast mana and doublers (Mana Flare effects, High Tide, rituals, Nykthos-style ramp) plus cost reducers to consistently hit thresholds early. Lean into a compact combo like Aetherflux Reservoir + cost reduction or an infinite-mana outlet through a big X-spell, and tighten the deck with premium counterspells and tutors (Mystical Tutor, Fabricate) to protect the plan and assemble wins faster.
