Providing fixing, ramping, and a flying chump-blocker (that can turn into an attacker if your deck packs enough buffs), this thopter is a great team player for any mana-hungry deck
My pick: Merlin - Crab Prince John - Greediest of All is another card that is better suited for Constructed because a typical Limited pool contains only a single discard effect
Sets like 151 catered to nostalgia, while Paradox Rift and Twilight Masquerade pushed competitive mechanics
The utility of a Chord of Calling you can cast after milling it is also quite nice
If a permanent card is put into your graveyard during your main phase and the stack is empty, you have a chance to cast it before any player may attempt to remove that card from your graveyard
You can pay three mana to give all of your creatures +1/+0 until the end of the turn, but the main ability is that Purphoros will deal two damage to each opponent every time a creature enters on your side of the battlefield
