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.

Cities in Dust
