Scion of the Ur-Dragon

This is an aggressive dragon combo deck that features a clean one-card combo and other unique treasure/commander interactions. Scion of the Ur-Dragon provides you with an impressive arsenal of options when he is on the battlefield. The main combo simply requires your commander, 4 colorless mana (two Scion activations), and one reanimator piece (Animate Dead, Necromancy, or Dance of the Dead) for the win. Combos explained below.

When piloting this deck, it is important to remember that when you activate you commander's ability, after that ability has resolved on the stack, you can no longer re-activate its ability until the end of turn (Scion becomes a copy of the creature thus loses its search ability).

What this effectively means is that if you are going for the main combo, you must choose between activating Scion's ability once per turn, or activate his ability multiple times in a row immediately after each other, by holding priority after his previous activation and activating his ability again as many times as needed in the same phase.

Main Combo (3 ways):

• Two Turn Takedown: Use two turns to complete the combo. Set up the combo during an opponent's turn by using Scion's ability to put Worldgorger Dragon in your graveyard. On your turn, play Animate Dead or Necromancy or Dance of the Dead targeting Worldgorger Dragon (for infinite land untaps/mana). Then, simply activate Scion's ability to become Bhaal's Invoker for the win. Important note: Worldgorger Dragon + reanimator piece is an unstoppable loop and forces a draw if not interacted with. Stop the combo by a counterspell targeting the reanimator piece, removal spell targeting Worldgorger Dragon, or have the reanimator piece target another creature in a graveyard when it enters the battlefield.
• One Turn Takedown: Take out your opponents in a single turn. On your turn, you'll need to activate Scion's ability twice in a row (immediately after each other in the same phase), searching for Bhaal's Invoker then Worldgorger Dragon. Play Animate Dead / Necromancy / Dance of the Dead targeting Worldgorger (for infinite land untaps/mana), and close the infinite loop by having the reanimator piece target Bhaal's Ivoker, bringing it onto the battlefield. Dump infinite mana into Bhaal's Invoker for the win.
• On The Hunt: If you are in need of a reanimator piece, you can have Scion become Ancient Silver Dragon (or Dragon Mage) during the declare blocker step in an attempt to draw one. If you have enough mana, you can activate Scion's ability 3 times consecutively, ditching Bhaal's Invoker, then Worldgorger Dragon, then Ancient Silver Dragon. If you happen to draw a reanimator piece from Ancient Silver Dragon, you can pop the Worldgorger Dragon + reanimator piece combo to generate infinite mana and close the infinite loop by having the reanimator piece target Bhaal's Invoker, bringing it onto the battlefield. Dump infinite mana into Bhaal's Invoker for the win.

There are so many possibilities with this deck, it's impossible to list them all here. Interesting note: If Bhaal's Invoker is not available in the above combo, Swashbuckler Extraordinaire can be used instead for infinite Treasures.

Greedy Dragon combo:

Mycosynth Lattice + Scion of the Ur Dragon’s ability to copy Hellkite Tyrant. Yea just steal ALL of one player's permanents if you can hit combat damage - Rogue's Passage / Veil of Secrecy can help.
