Casual Version:

Sparkmage Aggro | by @Metroidpikmin. (curiosa.io)

The plan is to use [[Sparkmage]] offensively, using cantrips and other low cost spells to play 1-2 spells a turn letting Sparkmage deal 2-4 damage. Before Minions are accounted for.

The key cards are teleport and blink, the deck wins with sparkmage, and getting Sparkmage close without tapping so you can use that ability is key. Kythera Mechanism is the best card in the whole deck, let's just get that straight. Sparkmage, Lightning Bolt, Thunderstorm, Headless Haunt, and Raise Dead all have the word random Mechanism puts in a lot of work, letting you hit what you want to hit. There are a couple of other notable cards, poisonous dagger lets Sparkmage kill any minion letting you deal with 5 plus power minions easily. Highland Princess grabs Mechanism or a core. Really all of the cards serve a purpose. With all the cards except the artifacts, blink and lightning bolt all being two air threshold puts a lot of work in. Gyre Hippogriffs are a great 4 drop as if you can use the Sparkmage ability for 4 mana you can deal 5 damage. They are also great for closing out a match

This deck is aggro, but not the win turn 3 or 4 kind of aggro. This is an aggressive deck once you have a mana you teleport near your opponent and start zapping them for 2-6 a turn. You can win fast but the deck wants to get to 4 mana and stay there. Then from there get close, cast spells to build up the threshold, and tap for damage. I love casting teleport, then lightning bolts and tapping to deal 3 with Sparkmage, if all of that hits the opponent's avatar you just did 6 damage in one turn, before taking into account minions you have out.

Try to place the stall sites, Great Wall, on row two to by you time to get to 4 to 6 mana. And don't be afraid to retreat with Cloud City or a Teleport if it keeps you alive longer, the Angel's Egg can do a lot.

Don't be afraid to hard mulligan your spells, you need teleports in your hand.

All of the minions in the deck are to help you keep pressure and let you deal 2 with Sparkmage.

Feel free to play around with the number of Phase Assassin and Haast Eagle the two are quite interchangeable. Phase Assassin is more on the aggro side because of Voidwalk, whereas Haast Eagle is a better defensive play especially with Updraft Ridge. Both are hard to remove because of the Stealth and Airborne respectfully.

Site Placement Strategies: I would recommend playing sites only in the back row, this lets you stall an additional turn before taking damage. If you play Great Wall as your first site it will stall out two turns as they would need to play 4 sites before their minions can attack your sites (unless they have airborne minions).
