Might want some outside opinions on that...
The psion combo is easiest to pull off...
Cost is 4
+ 4
+ 9
+ 1
= 18
A total of 4 cards so thats a bout 8
for a total of 26
converted
Have to give up shield slot, ~2
(I think...) so 28
converted
After that,
-> you will flood both sides of the field with psions about 5 turns depending on other creatures get played first.
-> There will be no way to stop the flooding, but sundial and SoP could slow it a bit.
-> Downside, you have to survive off of a mirror shield the whole time.
Propogation rate:
a = owners move, b= opponents move
Turn #friend #enemy
1a 1 0
1b 1 1
2a 2 1
2b 2 3
3a 5 3
3b 5 8
4a 13 8
4b 13 21
5a 23 21
5b 23 23
The lack of spell damage mitigation outside of mirror and emerald shield what makes this so nasty.
