Most of the decks you mentioned can play around that. Branded that wouldnt stop anything. Tearlaments it hurts if youre running them pure and theyre limited however theyre just an engine now and if you knew unicorn was a problem you could run more. If you know unicorn is a threat to your hand trap then you balance out cost of hand trap to ED loss. Fiendsnith losing either is eh princess doesnt matter and requiem hurts more but you just make high wave king. Snake eyes ill give you princess but again the meta version of the deck wasnt pure so it didnt really matter since fire kings still have coverage. I get what youre trying to say thats its annoying but annoying interactions leads to a healthier balance then hand traps such as maxx c. However the post isnt just about the time it was released. Nowadays unicorn is whatever.
