Crack in Time

Menace At the beginning of your end step, create a 3/3 black Dalek artifact creature token with menace if an opponent lost 3 or more life this turn. Then each opponent who lost 3 or more life this turn faces a villainous choice — You draw a card, or that player discards a card.

You may look at the top card of your library any time. Would You Like A...? — Once each turn, you may play a historic land or cast a historic spell from the top of your library. When you do, create a Food token. (Artifacts, legendaries, and Sagas are historic.)

Allons-y! — Whenever you attack, exile cards from the top of your library until you exile a nonland card. Put three time counters on it. If it doesn't have suspend, it gains suspend. Timey-Wimey — 7: Time travel three times. Activate only as a sorcery. (For each suspended card you own and each permanent you control with a time counter on it, you may add or remove a time counter. Then do it two more times.)

Paradox — Whenever you cast a spell from anywhere other than your hand, put a +1/+1 counter on target creature. Team TARDIS — At the beginning of your end step, untap each creature you control with a counter on it.

Rose Tyler gets +1/+1 for each time counter on it. Bad Wolf — Whenever Rose Tyler attacks, put a time counter on it for each suspended card you own and each other permanent you control with a time counter on it. Doctor's companion (You can have two commanders if the other is the Doctor.)

Whenever you cast a historic spell, investigate. This ability triggers only once each turn. (Artifacts, legendaries, and Sagas are historic. To investigate, create a Clue token. It's an artifact with "2, Sacrifice this token: Draw a card.") Doctor's companion (You can have two commanders if the other is the Doctor.)

T: Exile the top card of your library. Until your next end step, you may play it. Doctor's companion (You can have two commanders if the other is the Doctor.)

Whenever another nonartifact creature dies, return it to the battlefield under your control face down and tapped. It's a 2/2 Cyberman artifact creature. At the beginning of your end step, each opponent faces a villainous choice — Each artifact creature you control deals 1 damage to that opponent, or you draw a card and chaos ensues.
