Hi, Mages!
What about more Range +X cards? Not for Mages, because attack-spells rush decks will bee more powerful then, but for creatures?
1) Novice, for creature, ench range +1 for 2/3 mana. or +1 range and +1 piercing for more mana.
2) Novice inc, 2-3 mana for range +2/3.
3) Bottle for mage with 3 rage, add +1 range. 2 mana, 1 lvl nature
4) fire range attacks, ench that add d12 and 8+ Burn and fire tipe attack.
