1. Get http://www.wowhead.com/?item=45466 or http://www.wowhead.com/?item=47946
2. Use trinket, Spam 2 VT on your left side then 2 on right side. Depending on how your guild deals with adds u might want to SWP too, but this is some srs mana consumption.

Tell your disc priests to PI you during your trinket for maximum lolz 3 sec Mind sear.
Pro tips for not wasting DPS.
1. If you are in middle of area, dont dot, just flay/blast/death
2. If u are on side of area, vt/swp and proc replenishment whenever.
3. Dont try to Mindsear before Anub burrows u wont hit enough to make it useful, just multidot.
4. for the love of god dont mindsear off an add, absolutly no point faster adds die faster your entire raid will be dpsing anub, sounds better than 1 stand Mindsear tick.
5. Mindsear Glyph, get rid of Mindflay 1, it hurts a little on the inside, but you get used to it after a few attempts.
6. Be on the lookout for a good time to Mindsear swarming scarabs in burrow phases, i happend to get lucky on an attempt and was searing 5-6 targets.
7. Forget everything about dot uptime when adds are out.
Im tired, so that's all i can think of atm.
