You can get the only foil version surprisingly cheap, but it wont be cheap for long
The reality is that casting this card straight up isnt realistic in a Constructed setting
Running cards like Slither Blade, Triton Shorestalker, and Mist-Cloaked Herald guarantees you a ton of card draw, as they can easily slip past and deal combat damage
The other option is to take advantage of the direct damage, which is good in its own right to either finish off a damaged character or get them within range to be banished but also works with the likes of cards that benefit from being damaged - such as Scroop, Backstabber - that benefit from healing damage, like Rapunzel, Gifted Artist, or from damage being dealt: like Beast, Relentless.
Very powerful and doubly less narrow needing just the one colour and no energy support cards
[5] The classic example is something like, If I let you resolve your commander will you agree to not counter mine next turn? Basically, both of you get something out of it
