Overall, I think you can probably only play this card in a deck with repeatable sources of surveil
Then as long as you have 30 or more life, the dork gets indestructible to remove much removal interaction, only exiling mass removal or targeted non-destruction removal can get past this, and then it's +5/+5 size and then all damage to it is prevented
This green, blue, and red deck wants those massive creatures out quickly so theres a healthy mix of ramp, cost reduction for Dragons, and mana rocks to help keep you consistent
Hopefully, youll be fighting with Yiazmat rather than against it
But just one target - good against the archenemy in multiplayer on the first turn to take out their nasty combo piece and then showoff the person's hand to the others who need to take them out and down
On his own, he is a blue and black Dragon that costs six mana and enters with three power and five toughness in addition to the Deathtouch ability, which lets him kill any creature he damages
