Looks like this was the last warlord left without a thread - which had me wondering, since he is very interesting deckbuilding-wise, in my opinion.
Points of note:
- You want a number of units higher than average, since you need to be able to discard them reliably.
- You want some discard effects, possibly from both hand and top of the deck.
- You want some aggressively-costed units with weak textboxes ("vessels") and some units with a strong textbox ("ghosts") - even better if they're good as a whole, but the textbox matters the most.
Now the tricky part: how many of each?
I am not certain about anything, but I would restrict the number of "otherwise useless" ghosts to a minimum, otherwise the deck tends to become too unreliable. In addition to this, the fact the ability can be used only once per round means it's more of a strong bonus rather than something you can rely completely upon: if you have a bunch of mediocre vessels, you're going to be able to make only a single one into a strong unit.
Final point: the temptation to go all-in with units and forsake shields completely is strong, but I think it'd be a mistake, since shields are a cheap but powerful thing to have.
So, here is my stab at an Imotekh deck:
Imotekh the Stormlord
4x Court of the Stormlord
3x Parasitic Scarabs
3x Harbinger of Eternity
2x Decaying Warrior Squad
2x Inquisitor Caius Wroth
2x The Duke of Debris
3x Void Pirate
3x Rogue Trader
3x Mindless Pain Addict
3x Bloodied Reavers
3x Furious Wraithblade
3x Daring Assault Squad
1x Supreme Strategist
3x Dynastic Weaponry
2x The Strength of the Enemy
3x Mechanical Enhancement
1x Sautekh Royal Crypt
The only strict ghost is the Daring Assault Squad, whereas the only vessel that really necessitates a textbox swap is the Mindless Pain Addict (worst case scenario, you can use a Void Pirate).
Bloodied Reavers are a flexible unit, decent both when used as a Ghost and as a regular unit - the same goes for the Wraithblade, although its textbox is much stronger.
I'm sure there are still many possibilities to explore though, so I'm looking forward to playing more with the Stormlord.
I'm curious to read what you guys have come up with!
