Riku Storm / Wizardry
The deck originated from the synergies between Riku, Possibility Storm, instants and sorceries. However, with no real win condition, I added storm spells and some support. The list is currently stranded somewhere between a combo deck and a control deck.
The primary game plan is to cast ramp spells and draw spells early, setting up to have a good hand and a ton of mana when you untap with an enabler. You should almost always try to win if you untap with Wort, Melek, Riku, Volute or a mana doubler in play.
The deck plays all basic lands to enable early harvest, and because it's actually not uncommon to get every land in your deck in to play with ramp spells.
The 4 drop density is probably not optimal, but it feels so good to go turn three 4-drop, turn five Riku, turn six copied 4-drop.
To win, please employ some combination of the following:
- Very large Epic Experiment, preferably copied
- Mind's Desire. It is banned in legacy for a reason
- Loopable graveyard recursion
- Empty, Ignite, and Fissure
- Aiming as many copy effects at Eternal Dominion as you can. Each copy that resolves comes back every turn thereafter.
Notable cards:
Electromancer, Heartbeat, Mana Flare, Arcane Melee:
All serve the same purpose of letting you cast even more spells on a big turn
Wort, Melek, Riku: All 3 will almost always win you the game, but each have different tricks. Riku is probably the worst, due to the mana investment required to use him, but he's your general. Wort synergises really, really well with empty the warrens, and Melek is a card advantage monster.
Spellweaver Volute: A pet card. You can enchant other people's instants, and since it casts them, each time it triggers you get another storm count
Possibility Storm: Similar to Volute, it can supercharge your storm count. It also stops your opponents from being able to meaningfully interact with you, and combos with Riku thusly:
Spell 1 triggers both storm and Riku. Allow storm to resolve, casting spell 2, triggering Riku. Pay both Riku triggers. End result is 2 instances of Spell 2 and one of Spell 1, for one card.
Regrowth and Call to Mind: If you Riku copy one of these, and target the other, you can loop them to repeatedly (infinitely the other target makes mana) to recur your whole graveyard forever.
Mana Geyser, Turnabout, Rude Awakening, Early Harvest, Reiterate:
Any of these 2 card combo with Reiterate and enough starting mana for infinite mana and storm.
Cards worth potentially adding:
Cloud Key, Medallions, Helm as more mana enablers
Palinchron and Worldgorger Dragon 2 card combo with Riku to make infinite mana and storm
Restock is nuts when copied. Recoup and Snapcaster are cheap, copyable recursion. All 3 are single use, as they exile either themselves or their targets
Holistic Wisdom: I actually didn't know this card existed. It seems absurd, letting you do so much nonsense, since everything meaningful in the deck is a sorcery.
Recollect and Call to Mind act like more copies of Regrowth and Retrieval
Intuition and Mystical Tutor. Intuition piles involving Past in Flames are brutal
Time Spiral is actually not quite as absurd as it looks, since you can make very good use of your graveyard. Wheel of Fortune is bonkers. Frantic Search seems small, but would usually put you ahead on mana and dig you a bit deeper. Seems really nice to copy.
Zhur-Taa Ancient and Keeper of Progenitus are mana doublers you can copy with Riku for frankly absurd amounts of mana. Mana reflection is really good if you need even more.
Firemind's Foresight package: Getting Reset, Reiterate, and Bolt wins the game on the next main phase. It could also just go grab Mystical Tutor, Intuition, and any 2 mana instant to set you up to fight through disruption.
Bribery and Acquire are really, really good alternate win cons for this deck, because Riku can copy both the spell and both creatures you take. 2 Blightsteels and 2 Metamorphs copying Blightsteel for one card seems ok.
Ruination: Depending on the metagame the deck is played in, casting Ruination could just win. Since you run all basics, it doesn't effect you at all, and compared to Blood Moon, you can recur it more easily, tutor for it more easily, etc.
