Another thing to illustrate here with the hay-makers in the sideboard is the awkwardness of removal in this format
Compare it with a standard playing card or a credit card
Creature - Elf Druid Color tag templates(None) Bello, Bard of the Brambles During your turn, each non-Equipment artifact and non-Aura enchantment you control with mana value 4 or greater is a 4/4 Elemental creature in addition to its other types and has indestructible, haste, and "Whenever this creature deals combat damage to a player, draw a card." Legendary Creature - Raccoon Bard Color tag templates(None) Callaphe, Beloved of the Sea Callaphe's power is equal to your devotion to blue
It does go up in value in decks that have lifegain synergies (Vito, Thorn of the Dusk Rose or Karlov of the Ghost Council, for example)
Its easy to cast with just one blue mana pip and always results either in your opponents conceding or in them being tortured through a much longer game
The flexibility makes this card exceptional across all game states
