List advice for 'reunion tourney)

Hey legends. So my mates and I have all gotten back into hobby after a 15+ year hiatus. This weekend four of us are getting together to hold a casual 'reunion tournament', and this will be the first time any of us have played since.

I'm thinking of playing SSA detatchment with the attached list. Was going to give the hexmark with TSK chrono impedence, then demanding leader for the lokhust lord with the 6x destroyer block.

So far I am thinking: A) TSK block to hold middle and draw fire B) imotekh on home obj for CP generation with hexmark C) heavy destroyers + lord and reanimator for board support/secondaries D) destroyer block + lord for board support/secondaries E) tomb blades for harrassment

My main concern is that the TSK block may just be ignored given the insane durability with the hexmark, Reanimator, and Spyder, leaving the rest of the army to be quickly swept up while hitting secondaries.

I went a bit overboard with the 'treat yoself' purchases, so I have quite a few other units I can mix in.

1x Void dragon 10x immortals 10x deathmarks 2x triarch stalkers 40x warriors 2x overlords 2x technomancers 1x psychomancer 1x chronomancer 1x orikan 6x canoptek wraiths 6x skorpekh destroyers 1x doomstalker 1x annihilation barge/command barge 6x scarab swarms 10x flayed ones 10x lychguard

Obviously would like to be competitive but also just have fun.

Would love any advice/criticism/tips!

Thanks!
