“Kira, Great Glass-Spinner” is a blue creature that protects your creatures from being targeted. Similar blue cards:
- “Swiftfoot Boots” (artifact, grants hexproof and haste)
- “Diplomatic Immunity” (enchant, grants shroud)
- “Sigil of Sleep” (grants protection through bounce)
- “Sakashima's Protege” (flash & potential copy/protect)
- “Aegis of the Gods” (white/blue, gives hexproof to you)
- “Ward of Lights” (protection from colors)
Most direct blue equivalents:
- “Siren Stormtamer” (can counter a spell/ability targeting your creature)
- “Sakashima’s Student” (can disguise itself as another creature)
Reason: Blue has few direct replacements, but these protect creatures similarly.
