Viserai SAGE Precon Upgrades
Hey y'all, just recently got into the game thanks to the SAGE precons and been loving it all I'm seeing so far, so much so that I'm already in the process of building two other decks (and restraining myself from making them all Runeblades, since one is Florian and I also had my eyes on the Briar precon). Before I order the cards for Florian, I ask you guys what you would suggest to upgrade for the Viserai deck.
While I'm not having any specific problems per se with the deck or specific matchups (except maybe Kano - which seems a rather common issue - and Fai) I feel the deck could definitely use some tuning. I'm especially unconvinced by Runic Fellingsong, which more often is either a dead card in my hand or a mediocre defense on the opponent's turn. Which cards would you suggest putting in the deck and do you suggest other cuts? I've seen Shrill of the Skullform floating around as another potential card, and Scar for a Scar / Flying High (Red) as possible inclusions.
Thanks for the patience, I still don't know the game enough to make the replacements on my own and I haven't seen a lot of discussion about this specific topic, so I appreciate all the help I can get.
