Five cards with possible potential

Five weeks to easter and n00bcon! I'd like to mention a few cards that haven't really seen any play at all yet, but might make a splash this year. Last n00bcon we saw Relic Barrier make a huge impact, and during BSK we saw Haunting Winds take a player to the top4. We also had Petra Sphix and Field of Dreams in the top8 :)

1. Gaea's Avenger

Last year's winner played 24 artifacts maindeck, and it's not uncommon for the control decks to play 1/3 or more of the cards in their decks as artifacts. Facing a couple of Moxen and a Sol Ring, this is a 4/4 for 3, and it grows with your opponent's mishras as well. The fact that it's immune to City in a Bottle, and many times can play around lightning bolt, may make this guy fairly playable. The issue is of course that your opponent needs board presence to make him big, but as long as those artifacts are mostly mana I think this guy could make the cut.

2. Hyperion Blacksmith

This dude is a reasonable cheap 2/2 for 3, that can work double shift as someone who turns on your opponents Howling Mines or Winter Orbs when you need it, as well as tapping out his mana stones or threats. The 1RR mana cost may be a little restrictive, but I definitely think that this guy could be good enough, at least in sideboards.

3. Land Equilibrium

I have no idea how this should work, but I wouldn't be surprised to see this card somehow get it's way into Electric Eel aggro. Again, don't know how, but the effect looks very powerful, especially alongside Energy Flux and cheap threats.

4. Ice Storm

I guess this one was an easy pick. We've seen Stone Rain pop up in a lot of sideboards the last year, and I think that Ice Storm should be due. Almost regardless of your strategy, being able to kill a Library, Mishra or City is very relevant. Also, this one is harder to counter than stone rain (as BEB is heavily played).

5. Mana Vortex

A some point every year I spend a few moments to try to break Mana Vortex, still with no success. It has the feel of a (terrible) old school smokestack, but it never seems to work as expected. I just feel that there should be some Dingus Egg prison deck out there that can use Mana Vortex, and I'd love to see someone actually manage to use this.

There are lots of other potential tech of course, I myself will try to assemble a highly random Power Artifact deck (which obviously will win the tournament, power or none).
