Activated abilities are a huge part of the game across all colors and card types, so the question simply becomes "what can I do with two extra mana each turn?" It could be something as simple as activating Reckoner Bankbuster or an incubation token, or maybe something else entirely

Good oldies Overrun or Titanic Ultimatum should be game winners here
When you next attack this turn, untap each creature you control
