Firebend: Get red mana during combat step

Waterbend: Convoke, but for abilites

Airbend: Exile target object(s), owner can recast for {2}.

Earthbending: Target land becomes a 0/0 with X +1/+1 counters that is still a mana source. When it dies or is exiled, return to the battlefield.

I mean, the emergence of magic by no means makes religions obsolete, as most of them become casting traditions.

I mean, all evidence thus far of Mold infected individuals taking extreme levels of damage and regenerating from it hasn't turned out well for the subjects in question (Jack Baker/Lucas Baker/Alcina Dimitrescu) all mutating horribly when they get back up.

Any time I hear "Puppies are Forever" by Sia, it fills me with a undying dread and rage, even if I agreee with the message of the song.

If you're going to do funny drafts or more casual play without having to invest into decks, I would suggest using something like YGO Omega (omega.duelistsunite.org) as Master Duel is at least time intensive to get started, especially to get a card pool wide enough to do drafting.
