I had this idea while lying in bed. It's a control / combo list looking to bully the opponent with space and card advantage.

The Cities seem incredible with Elementalist because they provide 2 as soon as turn one. This results in early combo lines with Landmass.

Combos Going First

Any one of these combos will box your opponent into just their back row. This will provide a mana advantage over the course of the game and make it difficult for them to reach your avatar.

City + Earth Site + [[Landmass]] / [[Common Sense]] / [[Toolbox]]

• Turn 1: Play City to your starting location. If you have Common Sense, use it to grab Landmass. If you have Toolbox, play it to your avatar.
• Turn 2: Play Earth Site to the location ahead of you. Then cast Landmass, playing a site in front of your opponents starting location.

[[Sinkhole]] + Earth Site + [[Landmass]] / [[Common Sense]] / [[Toolbox]]

• Turn 1: Play a site (This does not need to be your Earth Site if you instead plan to play it turn 3).
• Turn 2: Play Sinkhole to the location ahead of you. If you have Common Sense, use it to grab Landmass. If you have Toolbox, play it to your avatar.
• Turn 3: Your actions depend on where your opponent plays their second site:
• If your opponent plays a site in front of their starting location (adjacent to Sinkhole), use Sinkhole to destroy it and play a site to the rubble where Sinkhole was. Then cast Landmass, playing a site in front of your opponents starting location (This is possible because the mana from Sinkhole is still "floating").
• If your opponent does not play a site in front of their starting location, play a site to that location. Then cast Landmass, playing a site in front of your opponent's last played site.

Tower + Earth Site + [[Landmass]]

• Turn 1: Play Earth Site to your starting location.
• Turn 2: Play Tower to the location ahead of you. Then cast Landmass, playing a site in front of your opponents starting location.
