Here's a tip: Mega Absol is a MINIMAL NEED. Without him, you'll be stuck using the weak Mega Sableye yet removing very few disruptions as well as a +5 moves. The reason Mega Absol is used over Mega Gengar is because of its ability to reset the disruption timer and deal massive burst damage with its effect. In addition, Mega Absol's effect can remove most of those unbreakable blocks after the 5-disruption timer. Get the Absolite through Mission Card 10.
I also include (both) Zoroark and Zorua for Sinister Power. If you trigger this ability, all Dark type damage is multiplied by x2 the amount, making Mega Absol absurdly powerful.
If you want to Mega evolve Absol faster, you have Umbreon for its mighty Mega Boost ability. If you trigger this skill, Absol will increase its Mega gauge by 3 extra notches.
Also, you need to find a way to remove all of those initial Cresselia icons, because this will make the level slightly more difficult if ones from columns 2, 3, 5, and 6 fell to the bottom of the board.
If all else fails, a +5 moves or (if you are using Mega Gengar) a Disruption Delay will do.
Oh and, recommended level: 6
