Jadzi Combo
Commander (1)
Combo (8)
Tutor (9)
Approximate Total Cost:
In case the combo isn't obvious:
1) Get Chain of Acid.
Note: Drift finds Solve the Equation, Spellseeker finds Mystical Tutor, Merchant Scroll finds Mystical tutor, Dizzy spell finds Mystical Tutor.
2) Get Jadzi, Oracle of Arcavios on the board, probably using journey to the oracle.
3) Cast Chain of Acid targeting your own tapped land
3a) If you reveal a land, tap it for mana and copy Chain of Acid. Return to 3.
3b) If you reveal a spell, pay 1. Return to 3.
Note: you may notice that, while the huge number of lands virtually guarantees we'll be mana-positive here (each land hit giving +1 mana, each spell giving -1), we will eventually run out of lands to target with chain. This is the purpose of the storm spells, as each of them will give a huge number of triggers from Jadzi, thus dumping a bunch of lands in play. Alternately, if you hit Darksteel Citadel or Cascading Cataracts, just keep targeting that.
Note: the storm counterspells must be cast targeting chain of acid, but not to worry - all the copies can target the original counterspell (which you obviously decline to pay), so you don't actually need to pay any mana to keep Chain of Acid resolving.
Note: you should fail to find with sprouting vines. More lands in deck = more storm count.
3c) If you're about to reveal nothing because you ran out of cards, proceed to step 4.
4) Flashback Memory's Journey, putting Brain Freeze, Hunting Pack and Temporal Fissure back in the deck (Serene Remembrance is an alternative).
5) Cast those cards off the chain of acid....chain, emptying enemy decks and battlefields and putting ~110 beasts into play.
Note: steps 4 and 5 may be unnecessary depending on when you hit those storm spells in your normal chain
6) With Akroma's Memorial in play, attack and kill everyone.
7) Now that everyone is dead, they die a second time to being decked out.
8) Stop playing Jadzi probably.
There's probably a more competitive version of this list running a little ramp to hit Journey T3, and some protection for the combo (be careful it's modal or something, though, or it could get stranded on top of your deck and break your combo). This was just the simplest version of the deck I could think of.
If you want to make the deck more reliable, here's some ideas:
Viable Counterspells
Approximate Total Cost:
Also, any protection spells for Jadzi that give hexproof or whatever are fine. Counterspells like Mana Leak are safe-ish but they might terminate your combo if you have bad luck and hit multiple off the top, hence why I only list those with X.
