AI searches for currently irrelevant cards using Treefolk Harbinger

[MorihiroS]

Describe the bug
Using Treefolk Harbinger, AI searches for Ancient Lumberknot/Doran, the Siege Tower with only three/two lands in hands. Or AI searches Ancient Lumberknot when it has Doran, the Siege Tower and only 2 lands in hands. It also searches for Ancient Lumberknot in first but Doran, the Siege Tower is better.

To Reproduce
Steps to reproduce the behavior:

1. AI has 2 lands in hands and no Doran, the Siege Tower
2. AI casts Treefolk Harbinger
3. AI searches Ancient Lumberknot
   or
4. AI has 2 lands in hands and Doran, the Siege Tower
5. AI casts Treefolk Harbinger
6. AI searches Ancient Lumberknot
   or
7. AI has 3 lands in hands and no Doran, the Siege Tower
8. AI casts Treefolk Harbinger
9. AI searches Ancient Lumberknot

Expected behavior

1. Using Treefolk Harbinger, AI should search for third land if it has 2 lands.
2. AI should search Doran, the Siege Tower rather then Ancient Lumberknot. And it must search Ancient Lumberknot only if it has Doran, the Siege Tower in hands/on the battlefield and it has 4 lands.

@Agetian when searching, AI should prefer more castable cards
