▸Stax-locking the table while a hard-to-kill threat chips them out
Archetypes
Big Mana / Eldrazi Ramp — Ulamog rewards stacking colorless ramp to cast it and other titans early.

Combos
No combos found for this commander on Commander Spellbook.
When you cast this spell, destroy target permanent.
Indestructible
Annihilator 4 (Whenever this creature attacks, defending player sacrifices four permanents of their choice.)
When Ulamog is put into a graveyard from anywhere, its owner shuffles their graveyard into their library.
Ramp hard with colorless mana rocks and big-mana lands, then deploy Ulamog to wipe a key permanent on cast and crash in with Annihilator 4. As a colorless commander you build a Commander tax/Eldrazi shell that punishes opponents with massive creatures and protects your board while overwhelming with size.
Indestructible and shuffles back when it dies, making it extremely resilient to removal
Free permanent destruction every time you cast it, plus crippling Annihilator 4 on attack
Colorless identity means it slots into any deck and stresses no color requirements
Annihilator 4 ends games fast once it connects
11 mana is a massive investment; you brick if ramp is disrupted
Vulnerable to exile, bounce, and -X/-X effects that bypass indestructibility
No evasion natively, so it can be chump-blocked all day
Colorless identity locks you out of true interaction, card draw, and tutors from colored cards
Slow starts leave you defenseless before Ulamog lands
