Welcome to another spicy EDH brew! This Yidris, Maelstrom Wielder deck looks to sculpt its way to a turn where it can take infinite attack steps through the use of cards like Aggravated Assault and Hellkite Charger.
The Main Strategy:
This deck is trying to assemble Aggravated Assault or Hellkite Charger alongside one of the following cards: Sword of Feast and Famine, Bear Umbra, Savage Ventmaw. Most games start with you ramping using green based mana. Later when you connect your combo you end up with a enabler that lets you take extra attack steps alongside a card that lets you generate the mana to abuse the enabler.
How Does Yidris Fit In?
Yidris’s cascade trigger lets us go through our deck and cast more spells without spending more mana. He lets us cascade into tutor effects like Demonic Tutor that lets us tutor combo pieces right to our hand or we can use cards like Mystical tutor or Reclaim to put cards on top of our deck to cascade right into. In short – he’s an attacking value engine!
If Yidris falls in battle don’t worry – you are playing a ramp deck and can cast him easily again. You also don’t require Yidris to win the game. He just gets you value to setup your combos.
Understanding Cascade And How It Fits In
Cascade says “When you cast this spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom of your library in a random order.” You don’t have to cast the spell when you cascade into it (even though you usually do want to cast into it).
Whenever you cast lower spells after you have a decent chance to hit one of our tutoring effects that can find part of the infinite attack combo you are missing.
Cascade also serves as an alternate win condition for this deck. If our infinite attack cards are constantly getting denied we can outpower our opponents by getting tons of value off of cascade and eventually closing the game out with Avenger of Zendikar and Craterhoof Behemoth.
The Time Warp effects can be especially devastating to cascade into because they let you have access to another turn where you might be able to setup a more elaborate cascade trigger with Yidris. Using cards like reclaim you can take multiple turns in a row.
When you want to setup cascades to cast the spells you know about in your hand or near the top of the deck (off of a ponder or Scroll rack activation for example) I recommend casting all spells that setup cascade while the Yidris trigger attack trigger. If you do it while it is on the stack you don’t risk your cheap 1 cmc setup spells (that usually don’t cascade into anything other than Mana Crypt or Ancestral Visions) from messing up the order of your known spells.
By waiting for the Yidris trigger to go on the stack you also avoid your awkward moments lik your opponents removing Yidris before Yidris can deal combat damage. All of your cheap setup effects are instant speed so you can afford to wait for Yidris’ trigger to go on the stack before setting up.
