In fact, the first appearance of a gnome in Magic was as a red creature in Legends (Quarum Trench Gnomes I know, not the most auspicious beginning)
Ambiguity One of my pet peeves with Magic is that certain words are used to mean multiple things
Then exile this spell.) "Harmonize [cost]" means "You may cast this card from your graveyard by paying [cost] and tapping up to one untapped creature you control rather than paying the spell's mana cost," "If you cast this spell using its harmonize ability, its total cost is reduced by an amount of generic mana equal to the tapped creature's power," and "If the harmonize cost was paid, exile this card instead of putting it anywhere else any time it would leave the stack." Tapping a creature won't reduce colored mana components of harmonize costs
It requires a tapped creature in play, its a sorcery-only activation, and it costs mana to use, but the ability is all upside on a Seaside Citadel, and huge upside at that
Learning doesn't make up for a bad card and so this shouldn't be something people want to play
