I don't think you'll have problems with Grand Ma Mas with normal effort. I'd play Look inside, m2m against him. ;)
I think you should save ent for Red Bull Lakers. But, if he doesn't have any ent, I would better play normal. Low post, 2-3 maybe ;)
And if you go to the finals, I guess Tong Tong will be waiting there so now would be time to use ent. I dunno - Low post, m2m, crunch? ;)
