Maskwood Nexusutility$2.93It gives all your creatures every creature type, serving as a broad tribal enabler like Runed Stalactite but for your whole board. It also creates Shapeshifter tokens, giving it extra utility beyond the original equipment.
Amoeboid Changelingutility$0.46This creature can turn any creature into every creature type, closely matching the type-changing part of Runed Stalactite. It is a cheap repeatable tribal fixer for creature-type synergies.
Conspiracyutility$0.44It changes the creature type of your creatures as they enter, making it a powerful tribal enabler similar in function to Runed Stalactite. Unlike the equipment, it affects your entire creature base rather than one creature at a time.
Arcane Adaptationutility$3.49This is one of the closest functional equivalents for tribal decks, making your creatures share a chosen type. It provides the same type-fixing role as Runed Stalactite with a larger global effect.
Xenograftutility$0.62It gives all creatures you control a chosen creature type, directly overlapping with the tribal-enabling half of Runed Stalactite. The effect is global rather than tied to a single equipped creature.
Unnatural Selectionutility$0.25It can change any creature's type, which is useful for tribal synergies and creature-type manipulation. It is more flexible than Runed Stalactite, though it does not grant the power/toughness boost.
Cover of Darknessutility$13.89While not a type-changer, it is a tribal payoff that works best when your board is all one creature type, similar to what Runed Stalactite supports. It helps creatures of the chosen type connect in combat.
Obsidian Battle-Axeutility$0.38This equipment also supports tribal decks by giving an equipped creature a bonus and benefiting from creature types. It fills a similar cheap equipment slot for creature-type-focused strategies.
