When Challenging Pupil enters, conjure a card named Fatigue and put it on top of your library. (It's a colorless sorcery that costs {2} with “Draw a card.”)

First strike, haste
Wanderlust — At the beginning of combat on each of your turns, if you control four or more differently named lands, you may pay {1}{R}. If you do, create a 4/4 red Dragon creature token with flying and haste. Exile that token at end of combat.

Target creature gets +2/-2 until end of turn. (Then exile this card. You may cast the artifact later from exile.)

Gain control of target creature until end of turn. Untap that creature. It gets +1/-1 and gains haste until end of turn.

Double each number and amount of target instant or sorcery spell, activated ability, or triggered ability. Its controller may choose new targets for it. (Amounts are number words, X values, and “a” or “an” used as 1.)

Chaosphere Ravager attacks each combat if able.

For each creature target player controls, that player flips a coin. If the coin comes up tails, that player shuffles that creature into its owner's library.

{R}: Charbelcher gets +1/+0 until end of turn.

Flying
Vanishing 3 (This creature enters with three time counters on it. At the beginning of your upkeep, remove a time counter from it. When the last is removed, sacrifice it.)
If Chronowing Phoenix would die while it had no time counters on it, instead exile it, then return it to the battlefield.

Mentor (Whenever this creature attacks, put a +1/+1 counter on target attacking creature with lesser power.)

Whenever a player casts a spell, Cinderhoof Minotaur deals 1 damage to that player.
Whenever Cinderhoof Minotaur attacks, add {R}. Until end of turn, you don't lose this mana as steps and phases end.
