The Commander

Whenever you cast a spell during an opponent's turn, you get an experience counter.

Whenever Katara attacks, you may draw a card for each experience counter you have. If you do, discard a card.

Guide

Gameplan

Cast spells on opponents' turns to stack experience counters, then swing with Katara to refill your hand with a massive looting draw. You play a tempo-control game with flash threats, counterspells, and instant-speed interaction, building card advantage that fuels a finisher.

Strengths

Cheap two-mana commander that snowballs card advantage every game it attacks
Rewards interaction you'd already want to run (counters, removal at instant speed)
Mono-blue gives access to the best card draw, counterspells, and tempo tools
Experience counters persist through Katara dying, so the engine is hard to fully shut off

Weaknesses

Katara is a fragile 2-power body that must connect to draw, inviting removal and blockers
Loot effect forces a discard, so it's card-neutral unless counters are high
Mono-blue lacks efficient creature removal and struggles against go-wide boards
Needs to untap with Katara and a clear attack path to get value, vulnerable to a slow start
Wheels and discard-matters payoffs are limited in mono-U

Key Cards

Archmage Emeritus — Doubles up your instant-speed casting into extra cards alongside building experience counters.
Aetherflux Reservoir — All your reactive spellcasting gains life and can fire off a one-shot kill.
Mystic Sanctuary — Recurs your best instants to keep casting on opponents' turns and ticking up counters.
Rhystic Study — Generates the raw card flow to always have an instant available during opponents' turns.
Aqueous Form — Makes Katara unblockable so the draw trigger reliably connects.
Snapcaster Mage — Flash spell that builds a counter on opponents' turns while recasting interaction.

Upgrade Path

Lean into cheap, high-impact instants (Fierce Guardianship, An Offer You Can't Refuse, Swan Song) and magecraft payoffs like Archmage Emeritus to maximize off-turn casts. Add unblockable enablers (Rogue's Passage, Spectral Sailor's evasion analogues) so Katara always connects, and include fast mana plus tutors to assemble Aetherflux Reservoir or a Thassa's Oracle line for a tighter combo finish.
