Combo 1:

Wirewood Channeler 3G
Creature - Elf
Tap: Add X mana of any color to your mana pool,
where X is the number of Elves in play.
2/2

Pemmin's Aura 1UU
Enchant Creature
U:Untap enchanted creature.
U:Enchanted creature gets flying until end of turn.
U:Enchanged creature can't be the target of spells or abilities.
1:Enchanted creature gets +1/-1 or -1/+1 until end of turn.

The trick here is to have the Channeler out in play, along with another elf. With the Aura enchanting the Channeler, tap it to add 2 blue mana, use 1 to untap it, tap it again for another 2 blue mana, use 1 to untap it, tap it again for anoter 2 blue. Continue this tap/untap routine to gain access to unlimited mana.

You can use this unlimited mana to do many things. You can play your entire hand if you wanted. Some little tips could be to play spells with X in their cost, such as Blaze, Stream of Life, etc., or you can also play this little combo.

Use either Burning Wish or Cunning Wish to retrieve the other Burning/Cunning Wish using the unlimited mana, then use a Storm spell, such as Brain Freeze.
