I wish he was playable in standard. Wild is to much aggro for me to pull him off :(
Well if all you want is counter aggro and have enough time to play yogg, just play a lot of healing/armor cards, don't try to build a real deck.
Aggro is the easiest archetype to counter if you're not at all trying to compete against other archetypes. Especially in Wild where there are tons of good "sustain" cards. Just play 29 of these cards (preferably spells of course) + yogg.
Maybe put in there some anti secret tech otherwise secret mage will bully you of course, because having mana cheating on half your cards is stronger then heals and taunts.
