This deck took me from D3 to Masters unexpectedly fast (final 20 matches listed in Match History). Perhaps I got lucky with matchups, or others were just struggling to figure out what to play after the Endra nerf, but either way it was great :D
Like with other
Dramatist's Mask decks, you try to cheat out OTK units the turn after mask is played. This requires having very few units other than the one mask gets played on (
Jennev Merchant) and the ones you're trying to cheat out (mainly
First Flame). So the deck is primarily removal, draw, sites, and some counterspells.
Generally, I grab
Mirror Image from the market. This allows you to copy the big units when they get played, as they don't always provide an OTK. It works really well with all 3 of them for different reasons. However, if I feel the opponent has ample removal in hand, I'll opt for
Swift Refusal to help keep the merchant alive.
Games have been won without the combo as well. Either from Site units, weapons, or most commonly by tutoring a 7 cost
Molot & Nakova.
One tip I'd suggest is using Wisdom/Forge at the end of your opponent's turn, to feint having fast spells ready during their turn. This is generally only when you are low on power still and won't be able to play the cards they draw in the same turn anyways. I suppose that's a pretty general tip for Eternal all around but feel it certainly applies to this deck.
Also, a 4th First Flame might be good to have, but I didn't feel like crafting 4 lol.
