The Sunchaser Golem cycle I designed is hideously not-common. I've redesigned it:
Ouphe Replica –
Artifact Creature – Ouphe (C)
, Sacrifice Ouphe Replica: Put a 1/1 green Spawn creature token onto the battlefield.
, Sacrifice Ouphe Replica: Put a Relic artifact token onto the battlefield.
1/1
Gravity Mage –
Artifact Creature – Golem Wizard (C)
, Sacrifice Gravity Mage: Up to two target creatures gain flying until end of turn.
, Sacrifice Gravity Mage: Up to two target creatures lose flying until end of turn.
1/2
Sunchaser Golem –
Artifact Creature – Golem Cleric (C)
, Sacrifice Sunchaser Golem: Destroy target artifact.
, Sacrifice Sunchaser Golem: Destroy target enchantment.
2/2
Bloodgear Bruiser –
Artifact Creature – Vampire (C)
, Sacrifice Bloodgear Bruiser: Creatures you control gain lifelink until end of turn.
, Sacrifice Bloodgear Bruiser: Creatures you control gain deathtouch until end of turn.
3/3
Lurker in the Muck –
Artifact Creature – Leviathan (C)
, Sacrifice Lurker in the Muck: Destroy target creature.
, Sacrifice Lurker in the Muck: Destroy target noncreature permanent.
4/4
Sorry, but I couldn't add the original version to the spoiler in good conscious. It just wasn't common. Hopefully this is better.
