Combos Utilizing Candelabra-of-Tawnos

discard to untap key/academy to untap candelabra

Play the Flare, then the Candelabra, tap a land, and you can then untap 2 lands. Infinite mana, so Fireball, Braingeyser, Drain Life, Alabaster Potion or whatever. Bonus: no more mana burn!

since candelabra is mono, u must tap it. so tap to untap tol. acad., return candelabra to urhand, play again. must have a few artifacts out to continuously use tol. acad. to get infinite mana

with all urza's lands in play, they provide 2 colorless each. tap them to untap x target lands (x=twice the number of urza's lands tapped)

tap all your lands. use 1 of the mana you use from each of the lands to untap them and still have 1 left over from each tap. infinite mana!

verdant field the forest, and untap it using another land and the candelabra. It's like all your land have verdant field on them.

With one more artifact in play, tap Tolarian Academy and untap with Candelabra. Repeat it three million times, for example. Voilà!

use candelabra and 1 other artifact to get academy producing uu and use it with tawnos to tap and untap itself 100 trillion times for a good stroke

the candelabra is a mono artifact so its ability is actually "x, tap: untap x target lands". it cannot be used for infinite mana unless another source untaps it - most of the combos here don't work!

with this and 12 other artifacts you can gain endless mana and force you're opponent to go into his scoop-phase
