Which of the spoiled cards of set 2 is everyone excited for picking up in the AH? Obviously not even close to everything has been spoiled and there are still bombs to be shown that entire decks might be based around, however we can still theorize.
List of rares/legendary cards so far:
http://hex.tcgbrowser.com/#!/cards/rarity=r&rarity=l&set=sd
For me it's:
1. Wrathwood Master Moss - Best card revealed so far at the legendary slot. 5/5 for 4 that becomes a 2/2 when it dies. Said 2/2 has the chance to transform back into the 5/5 if it deals combat damage or is somehow reverted (Neat is that you can Trick of Light this card when it's attacking with the 2/2. Even if they use removal in response..trick still draws you a card so it is a 1-1 trade. They're forced to block the mini-moss or you get a free Master Moss so by tricking in response you're bound to kill a troop with the reverted 5/5 in the process).
2. Hopeheart Unicorn - In an extinction format, this card is obviously a god send. The 3/3 stats make it fit outside of burn range which is very relevant. The problem is that a diamond troop heavy strategy isn't really good right now. Tons of cards to be revealed to change that though (there are already some) and the card isn't going anywhere.
3. Crackling Vortex - Awesome card. Dual shard decks are sorta expensive in their threshold costs so I'm not sure how much not gaining a threshold matters but a resource that is 1/2 of a free card (2 charges on a 4 charge ability like Gozzog and Poca) is really nice.
4. Filk Ape - While revert hasn't been the most prevalent anti-permanent mechanic so far, having it done on an aoe scale is great. Card needs to survive until the end phase however which means against certain match-ups it could be a bust. Also can be used with your own transformations to turn cards back to their original form (Izydor/Vampire King's Vamps/Moss/Zombie Plague as a few ideas. PROBABLY not corrupted afterlife lol.)
5. Izydor - I want to like this card but I'm really not sure how good it is. The text is blurry so the cost of using the one shot is unknown but apparently it is 5. That's really expensive but maybe do-able. I'm interested in a wild/blood midrange filled with Vamps, Mosses, Izydor and the like with some revert cards (Trick of Light/Filk Ape?). It's a deck I REALLY want to make work but I can already see how it could be rather gimmicky. If the concept doesn't work, Blood/Wild still has the best midrange troops in the game so far so it's not like I'll be wasting much money.
6. Forge of Cadoc - While the card might not see use right away, it has a high potential for future use. Especially considering that in the digital space we can create cards in our hands. Possibly a simple 1/1 robot can be added to the hand easily and be used for this cards cost. Might not pick it up right away since I don't expect instant use out of it in any good decks.
7.Fury of the Mountain God - Possible super scary card. Obviously a lot better if you open with it but it's to be noted that you don't even need the troops to deal combat damage as the cards that ping you for 1 at the start of your turn will reduce his cost and so will cards with sockets that deal direct damage. I'll need to see it in action to really judge it.
8. Highland Shinobi - 2/2 swiftstrike for 2 AND will exhaust a troop every time you play a shard. Any Diamond aggro decks best friend. I'm curious if the card will exhaust 2 cards when you play Crackling Vortex. Considering you gain both charges at the same time, probably not.
9. Drowned Shrine of Ulthar - The card might not seem great in that it's not reactive, however because of the champion system it can be always live against certain match-ups. It's worth picking as a side deck option against future decks without easy artifact removal.
10. Junk Bot - No competitive reason. Just a silly card. Same with Eternal Drifter.
Honorable Mentions: Noble Heart, Rise Again, Mass Poly Dingler, Prince Talysen, Aborean Rootfather, Stonetusk, Royal Den Mother- Cards that aren't major wants for me but I think are good cards. I know I'll try to make a deck with Prince because of how badly I want to play a Mastery of Time for free. Also I'll make a separate deck with Rise Again since I like revival strategies.
Zeedu wasn't included because I am 99% sure the text was changed to better reflect the new "Replica" mechanic instead of just cloning cards. Also the current text kinda sucks since he has to deal combat damage before doing anything unlike Uruunaz.
I'm not a huge fan of any of the tunneling cards shown so far. Guess I'll have to try it before I really judge it.
