One of our greatest strengths is our ability to essentially semi-tailor on the spot towards our opponent through those random Gifts.
One fun thing to try out with Pinkies
btw;
18 w/full command + Blasted Standard + Aetherblade (or Staff of Change vs. non-
MEQ's). Attach a Tzherald w/Greater Locus of Change + an Exalted Flamer
Take Prescience + a pair of Malefic powers on the Tzherald, and it's a really fun little unit to throw onto midfield objectives! The Locus will occasionally backfire sure, but there's honestly nothing like watching S5/S6 Horrors rip it up in combat, all the while the unit's Tzherald summons in added reinforcements tailored to the situation at hand!
The Exalt can provide some heavy-hitting firepower with his D3 shot Lascannon, while his template shot will auto-activate the unit's Blasted Standard vs. the first attempted assault against your Pinkies... people don't really expect Overwatch from Daemons, so it can be a really nasty shock to suddenly be eating D3/S5/ap3 +
2D6/S4 auto-hits.
Definitely not a hyper competitive unit, but it is a super fun unit that'll give plenty of laughs.
I love to give that unit's Tzherald a Greater Gift which gets defaulted to the Mutating Warpblade, simply because it's the closest ability we have to the previous codex's Gift of Mutation power which turns enemy characters into Chaos Spawn!
With Prescience up, the Tzherald is fully capable of killing most unit Sergeant type characters to get the Spawn-farm growing...
