Notes & Combos

After the recent update, the format is much more enjoyable to play, especially because of the most recent pack and some new decks surging up in popularity.

I've started the season with only 1 Triple Tactics Talent and Dotscaper, but towards reaching M2 I've decided to switch it up a bit (no Dotscaper and 3 Talent) and again one last time (Dotscaper and 3 Talent) before hitting M1. Dotscaper's still decent in this deck, but not necessary, although in the situations it comes up it does help with extension, like a lot. Triple Tactics Talent was just insane throughout the whole climb, and drawing multiples didn't feel that bad because you could always discard the extra copy with Backup @Ignister.
