You may play snow lands and cast snow spells from the top of your library.
Whenever another snow permanent you control enters, you may pay

. If you do, put a +1/+1 counter on Isu.
Guide
Gameplan
Flood the board with snow permanents to grow Isu and dig through your deck via top-of-library casting, then convert your snow engine into either an overwhelming counters-matters board or a giant Isu beatstick. You play almost entirely snow lands and snow spells so you can chain plays off the top, ramping and growing while doing it. Win by going wide with snow tokens, going tall with counters, or assembling snow-fueled value engines.
Strengths
- Built-in card advantage from playing off the top of your library every turn
- Snow lands are functionally free to grow Isu, so the engine is cheap to fuel
- GUW gives access to the best counters, ramp, and protection in the format
- Synergizes with strong existing snow payoffs like Marit Lage and Dead of Winter
Weaknesses
- Snow-only top-of-library restriction shrinks your viable card pool and lowers raw power
- Slow to come online and reliant on Isu staying on the battlefield
- Vulnerable to board wipes since the strategy invests heavily in permanents
- Mana-hungry: you must pay for each trigger to actually grow Isu
Key Cards
- Marit Lage's Slumber — A snow-permanent payoff that makes a 20/20 flier, easily the best single win condition in snow.
- Arcum's Astrolabe — Cheap snow artifact that fixes mana, draws a card, and triggers Isu while smoothing your top-of-library casting.
- Coldsteel Heart — Snow mana rock that ramps, fixes colors, and pumps Isu when it enters.
- Dead of Winter — A one-sided board wipe in a snow-heavy deck that doesn't touch your snow creatures.
- Rite of Replication — Kicked copies of a key snow permanent generate a flood of Isu triggers at once.
- Doubling Season — Doubles every counter Isu gains and turbocharges any token plan.
Upgrade Path
Lean harder into proliferate (Inexorable Tide, Evolution Sage) and counter doublers (Doubling Season, Branching Evolution) to make each Isu trigger snowball faster. Add more cheap snow rocks and snow lands to maximize triggers and top-of-library hits, and include protection like Heroic Intervention plus reliable evasion (Rogue's Passage) to close games. Tutors such as Hour of Promise (for snow lands) and Marit Lage's Slumber as a redundant haymaker raise consistency and ceiling.

Archetypes
- Snow Tribal/Midrange — Isu rewards packing the deck with snow permanents and lands for triggers and top-of-library value.
- +1/+1 Counters — Every snow permanent can grow Isu, pairing naturally with counter doublers and proliferate.
- Voltron — Isu can balloon into a massive creature, making it a viable equipment-and-protection beatdown threat.
- Value Engine/Card Advantage — Playing snow spells and lands off the top turns the command zone into a steady draw engine.
