The trade benefit would really only work if you played a minion on an empty board, then traded this. Otherwise you might give rush to something that could attack anyway. Maybe useful after you've had your board wiped. I'm pretty sure +2/+3 for 2 mana is also pretty good.

I really can't see this not being good. Well, maybe if all your choices are too expensive to play on the same turn, so maybe don't put this in a big deck.

Am I missing something or is Runic Carvings the only Choose One spell currently in Standard? Well, I guess this card was printed with future sets in mind.

So Duel! except both minions come from your deck. Could be interesting.

I'm not aware of beast decks dominating, so I don't know how useful this will be.

Weaker but also much cheaper Swipe. I don't see why this wouldn't be good.

An extra 4 damage after each weapon swing? Sign me up!

Possible free removal for playing quest Warlock normally? Seems good to me, at least until it dies since it only has 1 health.

I recall 1 mana summon 2 1/1s being good, so 1 mana summon 4 should be really good. As long as you have a buff to follow up with so they don't immediately die to a board clear.

I'm not sure what you would want to repeat with this card. At a glance, it appears battlecries aren't as powerful in Shaman as I initially thought.

I have no idea when you would want to equip this versus trade. I guess as long as you have a spell in your hand that you can't afford the current turn, trade, otherwise wait until you do, then trade. Your still paying 1 mana for a 1 mana discount, so there's that.

This might improve shadow Priest.

I'm not sure how many times you would have to trade this to be good. 2? 3? I think this will have to wait an expansion or so to be very good, since I don't think deathrattle Priest is really a thing right now.

I recall Paladin liking their buffs, so this shouldn't be bad.

Not really a whole ton of options for expensive spells right now. Putting minions in your deck weakens Refreshing Spring Water, and who uses Mask of C'Thun?

I don't recall deathrattle Hunter being a thing lately, but this card seems like it would be good if that archetype returns.

At 5 mana, you're going to want 2 or 3 beasts on the board for this to be okay. That might be too hard to pull off.

A 3/1 rush for 1 mana seems good. So does a 1/3 taunt, but maybe not quite as good.

I guess maybe it could clear a couple things against a swarm deck. I'm not sure how often it will be useful.

I guess 3 mana draw 3 isn't bad. Warlock can't do that without hurting himself. Though you have to spend 1 mana to trade if you can't use it when you draw it.
