Mulligans
If you open raid the sky temple its the only legendary necessary for this deck you can also probably just get rid of it. You basically want to drain your hand and play mana cyclone to get mad value in control matchups. Mulligan the quest against agro and look for flackmage sorcery and ancient mysteries. If you have him you could probably add ziliax. against agro anomaly can be really good with shooting star, and against control I predict that you should be able to hold some burst from the quest hero power and the mana cyclones and magic tricks. there really aren’t a lot of bad mage spells right now in standard, lowrolls would be lunas Pocket galaxy, book of specters and arcane explosion.
No Kirin Tor Mage ?
And even if it’s an epic, you might need Splitting Image for tempo plays
