after watching the video, I too was wondering what to do to keep thoughtspores in the game:
1)a brace yourself, block, or reverse attack is good for one shot attacks like fireball, but bad against sustained small damage(like from a [mwcard=MW1C37]Thunderift Falcon[/mwcard] or archer
2)[mwcard=DNJ03]Etherian Lifetree[/mwcard] and/or [mwcard=FWE06]Fortified Position[/mwcard](danger of zone attack if you clump them under it), combined with healing or regeneration([mwcard=MW1J15]Mohktari[/mwcard], [mwcard=FWJ08]Renewing Spring[/mwcard], thoughtspore with minor heal)
