15:19 the Wargrey should have unsuspended before going into WargreyX since the attack target changed. Very easily should have had 5 checks game 3. Luckily it didn't bite him in the butt, good games!
if I had a penny for every single time a I've seen gracenova player has used the koh and sayoh effect to regress and evolve on a level 5 after using rookie on level 4 I'd be so rich STOP DOING IT. USE THE ROOKIE INHERITED ON LEVEL 5 TO NET +1 MEMORY.
I think he would have enough memory to do the full Gracenova play if he had tucked the level 5 twice instead of the level 4. (i.e. needs 3 level 5 in hand to do that) Then he could make Diana, go to 0 memory, then play another red Tamer to go into Appolo. Would still die to the option in security, but at least would have cleared the Wargreymon.
