So I have been messing around with Niv-Mizzet Reborn in MtgA, and have found that decks that can use him well are very fun and powerful. So the format I play the most is legacy and I was wondering if anyone has any ideas or card suggestions for Niv in a legacy deck, so far I have been thinking of using him in a five-color combo deck and then using Niv to search for the cards, but I don't know what combo to use.
I had been creating this deck for a little while, building it off of decks I had found online. For some odd reason I thought it would be really cool to have the majority of the creatures in the deck to consist of dragons (as bladewing the risen is my fave card) so I just put in a bunch of dragons I had laying around into the deck to see what worked, initially using cards such as scion of the ur-dragon, nicol bolas, kokusho, the evening star and a couple more. Now that I have played with the deck for a while and making updates over time, I have found that the dragons I'm using don't have much value besides hitting the opponent once reanimated, are there any suggestions of valuable dragons I could consider using?
Thank you for any suggestions
Here is the deck in its most current form https://www.mtgsalvation.com/decks/10467-burning-reanimator-dragons
Thank you in advance for any help
