The only real catch is practicality, since it can be a little inconvenient if your opponents arent familiar with the card and need to check Oracle text
Its a 1/3 with vigilance and prowess as well as two activated abilities: a tap to loot, (draw, then discard) and yet another copy target instant or sorcery spell you control. The second ability can only occur if Kitsas power is 3 or greater, but in a fast Otter deck, that shouldnt be too difficult making this an exceptional engine for any decks that care about firing off tons of impactful instants and sorceries
Only a few, Eladamri's Call or Mystical Teachings, will get something at instant speed
Humanitys Vengeance Humanity's Vengeance is a Azorius deck that features humans fighting the monsters back
Though not nearly as impactful as the Altar itself, the sorcery speed Adventure attached to Altar of Bhaal, Bone Offering, can be cast for three mana, creating a 4/1 skeleton token with menace
The clan is a bit aimless and generally just winds up as a guild two colour pair archetype with a splash
