That explains it.
Discourse is screwing me over today, undeleting and unediting what I try to delete and edit, and I keep accidentally pressing Ctrl + Enter when just trying to make a new line. And maybe you can’t even read the edits here, I just assumed that is what you did as you commented much later.
As for your note on one-click wins, IMO that is the case for legendaries and 6+ mana cards, but not everything.
Anyway, first batch of critique on suggestions from current card design contest.
Like, really? Furor Chakram + Mass Flight for 3 mana?
Repeatable MDS for just 1 mana more?
Frostburn is 5 mana for just 1 damage more without any movement.
I might be missing something, but playing this in the center line and never moving is a nobrainer for me.
Fun fact: if the order of events is as in the description, it will not stop until something manages to survive an attack (which is unlikely).
Imagine this being played with Reva instead of Kaleos for a moment. One Heartseeker survives a turn, this, BBS, Heartseeker moves.
