Quite a good example to demonstrate haste and land placement mechanics.

You can normally only place lands adjacent to your own lands, or adjacent to a creature you control occupying an enemy land. Haste creatures can move, attack and gather Faeria on the turn they're played.

In this example you also have enough Faeria to cast everything from hand without worrying about gathering from the Faeria wells, but you do need to develop a 2nd desert before you are able to play the Rushing Wind. You also need to do 4 damage - so 2 of your creatures need to connect to face. With all this being said:

1) Play Khalim's Follower on the desert provided. As its haste action move 1 space North.

2) Use the 2x land action. Place 1 of those neutral lands north of your follower. Hold onto your second land placement. You do not need to use it straight away. You can play / move minions, cast spells and use it later on (right click to go back to the normal cursor after playing the first). This is the key to the puzzle.

3) Play the 3/3 Neutral Haste bandit on the land you just created. Use its haste action to move 1 space north onto the enemy neutral tile.

4) You can now place your 2nd neutral tile north of this, adjacent to the enemy orb.

5) Now you're out of land actions but you can create an additional desert using you air elemental's summon ability You can play this in the original tile that was vacated by the Khalim's follower. You can place the new land next to the enemy orb, adjacent to the neutral land you made.

6) Cast Khalim's follower on the new desert. It has haste so can attack for 2 damage.

7) You have 2 deserts, so now can cast Rushing Wind. Cast this on your bandit to move it adjacent to the orb and attack for the win (remember it has haste too).

Hope this helps
