Deckmaster: Aero Rover

This deck is revolving around getting max energy and draw through the whole deck multiple times.

Aero Rover's active skill allow you to burn redundant energy and convert them into ATK.
Aero Rover's passive skill allow you to gain some ATK as you spam modulate

Reroll for 1 cost cards that let you draw on the first turn

Firstly, Drop Sabyr Boar or Diggy Duggy if you have them.

Fusion Dreadmane + Diamond claw/Vanguard Junrock then Recycle is your main combo: Draw 2 + 3 extra energy. Repeat it as many times as you can.

If you don't have Fusion Dreadmane, just use any 1 cost card then put Diamond claw/Vanguard Junrock on top of it for draws. Dont burn the card if you do this. Only burn if Fusion Dreadmane is overlayed.

Burn some excess cards to summon 3 costs when you can't draw anymore. Prioritizing summoning Viltreum Dancer for even more draws.

Set up some Voltscourge Stalker and Electro Predator so that you can eventually modulate into a 3 cost Violet Heron. This 3 cost is particularly strong. Try putting the dog first in order to not lose HP.

Make sure questless knight has two different passives.

Repeat this combo until the end of the match, after you fill the field with 3 costs, just burn cards for mana then convert it to damage with rover's active skill. Support cards like Dwarf Cassowary and Chopchop headless are also very useful.

Ending a turn with Fusion Warrior in Frontline is nice for an extra draw next turn.

End game is when you summon Inferno Rider. Either by reaching turn 5 or losing enough HP. Try to keep your HP high enough so that enemy can't 1 shot you -key to beat Brant .
Just burn all your cards and use rover's skill every turn for the 3+ ATK to all. I beat the hardest mode very consistently.

Get nimbus wraith, overlay them to activate their passives, then spam transform to gain unlimited energy and advantage. Spam Zani active skill to get max damage.

This deck is much stronger than the first deck but the reason it is down here is because you can't play this deck right away. The first deck is available (more or less) right at the start.

Havoc warrior is a very useful card as it allows you to continuously overlay your draw cards on top of it to draw your entire deck and otk.

Defeat the 2 shopkeepers (silver helmet store and Solis), along with the guy who give you the questline who stand next to the fountain between the two shops.
