This clever loop turns Faeburrow Elder into a one-man mana powerhouse by exploiting its color-scaling mana ability, which generates five distinct colors thanks to its own multi-colored identity. By funneling a portion of that windfall into High Alert's activated ability, you can repeatedly untap the Elder for less mana than it produces. High Alert's passive toughness-scaling combat damage is a neat bonus, but its true brilliance here is acting as the engine that untaps your mana source, creating an endless surplus of every color.
