You can only use this effect of "ReSolfachord Dreamia" once per turn
Our counters and card draw are the same way, either proliferating to give our opponent more poison counters, like Reject Imperfection and Experimental Augury, or becoming super-charged once our opponent is corrupted, like Bring the Ending (which turns into an upgraded Counterspell) and Distorted Curiosity (which becomes a one-mana draw-two)
"King's Sarcophagus" passively protects "Horus" monsters from being destroyed by non-targeting destruction effects, and can send a "Horus" monster from Deck to GY, at the cost of sending 1 card from hand to GY, up to 4 times per turn - potentially preparing for all four "sons of Horus" to be Special Summoned from the GY
STEP 3: POTENTIAL So, youve figured out your identity what mechanic or aspect of Magic youre determined to recapture, the signature card effects youll use, even a fun joke name for the deck and you feel great pride and ownership in having built (or at least tuned it) yourself
This is highly recommended, as it will also give you access to other, even more exciting structure decks
