New Piltover & Zaun Spell - Poro Cannon

This seems pretty bad. For 1 more mana you can play rummage, discard 1 more card and draw 2 actual cards from your deck instead of Daring Poros. If discard decks really need a lot of discards to consistently discard their discard synergy cards then I could see this seeing play. This is the only way to discard at burst speed other than rummage, so maybe that gives this some hope. In a Poro or Von Yip deck, the Daring Poro is good enough that you might even want to run more than 3 of it, so in that deck I could see it being viable. Finally, as a zero mana spell it could be useful in a fizz deck.

Once you've eaten a couple of Poro Snax, Daring Poro becomes a huge threat. Creating two at once could be a strong finisher for that kind of deck.

Oh yeah! Since it discards 1 card to generate 2 cards, it's also not a net card loss like Warning Shot. 

In my various Poro experiments, the card draw and elusive offered by P&Z and Daring Poro were the most effective pair for the Freljord (even though Poros were still pretty bad...I haven't played seriously in a while, so maybe they're more reasonable since the Braum/Aurora/Herder buffs).

Clearly this is a good card in a deck that can use the Poros. Hopefully it's bad in most other decks, since it seems like a card that could is either trash or easily abused in less meme-y decks.

I actually really the synergy with L2 Nocturne: you can play the spell at any time for a free nightfall activation, then after he levels drop the 2x Daring Poro such that all allies have fearsome while all enemies have -2/-0.  I just don't know if that's a strong enough combo to carry an entire deck--especially if you lose access to the Targon nightfall units.
