A budget deck I made in q-mode which was chosen as a featured deck for the first Rings of Immortality season. Very good for completing the "win by your 7th turn" quest. The gameplan is pretty straightforward: burn enchantments early (to increase the likelihood of drawing them back with the Rainbow path), play minions, and hit face as much as possible. Minions with frenzy (Twinfire Zealot and Einherjar Berserkr) can hit twice per turn and are especially powerful when buffed with enchantments or vengeful heirloom. (Be aware though that Berserkr's frenzy ability needs to be activated first.) Use the divination from Serendipity Ifreet or Higher Ground to choose enchantments so you can draw faster.
Kara and Svinn are 4-drops with very aggressive statlines for their mana cost. Kara keeps growing whenever the opponent summons anything, while Svinn discounts your next enchantment and can also be moved anywhere (since he has the Teleport ability and your power is Impel). You can replace these 4-drops with Tailroot Wurms if you don't have them yet.
Einherjar Thane and Valkyrie Enforcer are there for support, to remove small and big minions respectively so your main attackers can keep going face. Thunderclap and Magnus Thorsson are for clearing boards filled with tiny minions, e.g. Eager Recruits, Strigoi Pups, or snakes from Serpent's Den.
Freki Sidecar can be used to rush in an attacker for a last-minute finish. A possible upgrade to this deck might involve swapping out the one Tailroot Wurm for Tyr Monomund.
If you don't win by turn 8 or so, you're probably dead. :P But then, that's the story of every aggro deck.
