So, in Feln fashion, the main weakness of this deck is needing the time to get rolling. Once turn 3 hits, the fun begins. It feels bad against hard aggro.
This deck is super fun in gauntlet, as the AI gets derpy with all the stealth. In pvp, the mystery of stealth can come in handy.
There's some card draw synergy to have
Jufi, Sprite Seer get rolling.
Also, there are tools to help win with
Sindar, the Corruptor. For example, endlessly filling your board using
Replication Cell, or finding ways for their hits to sneak by.
A little meme-like, but in general i like it for matches, as long as i am not blown up by turn 4. Feel free to comment :)
