Mulligan for draw with a dab of AoE. Always keep Prophet Velen.
Put a big emphasis on AoE when facing Rogue!
Keep the board cleared and keep collecting your combo pieces.
Pop off as soon as you have the 30 /15 (Alex) damage required.
Some cool combos:
Auchenai + Squashling = 12 damage / 7 mana
Prophet Velen / Malygos + Faceless / Mirage Caller + Alex + Mind Blast = 15-20 damage / 5 mana
Prophet Velen + 2 Faceless / Mirage Caller (any 2 will do) + Mind Blast = 40 damage / 5 mana
Prophet Velen + Faceless / Mirage Caller + 2 Mind Blast = 40 damage / 6 mana
Prophet Velen + 2 Faceless + 2 Mirage Caller + Mind Blast = 160 damage / 7 mana
The enemy drew and played his Malygos or Prophet Velen before you? No problem!
Cabal Shadow Priest / Faceless + Mirage Caller + Insert # of Mind Blasts needed.
Rinse and repeat!
