Time Spiral: Demastered is my love letter to WotC's love letter to the Time Spiral Block. All cards used are from Time Spiral Remastered. It's fairly straightforward - I used the 3-2-1 distribution for commons, uncommon, and rares/mythics respectively, and created a curated list of 48 of the Timeshifted cards that I wanted to include, then added some extra commons to support archetypes I wanted to show up more often.
48 packs breaks down to 8 commons, 4 uncommons, 1 rare/mythic, and 1 timeshifted card per pack, with an extra card of a random rarity other than timeshifted to bring it up to 15. 48 packs supports 16 players so you can do two 8-player drafts or four 4-player drafts, or a bunch of Winstons.
Relevant mechanics and archetypes include:
Suspend: appears in all 5 colors. Pay a little now to get the effect later, or a lot to get it immediately. Synergizes great with Storm!
Slivers: are in all 5 colors, but centered in Naya colors. Slivers from this set also share abilities with ones your opponents control - everyone has to play nice.
Morph: appears mainly in blue, with a few in red and green. Cards with morph can be played face-down as 2/2 creatures for 3 mana, and then turned face-up any time you have priority for an added effect.
Madness: appears mainly in black, with one card in red. Discard a card with madness and cast it for a separate cost as you do so.
Split Second: appears in all colors. Players can't cast spells or activate abilities while spells with Split Second are on the stack.
Rebels: appear in white and black. A bit weak to be a full deck on its own, but activating the Rebel tutor ability to grab Bound in Silence at instant speed is pretty fantastic.
Bounce/Flicker: white and blue. Bounce your own things for profit. Reality Acid control is fun to play and miserable for the opponent.
Saprolings/Go Wide: mainly in green, but black and white have some support as well. Slimefoot is a great piece for the deck if you get him in a Timeshifted slot.
Overall, the set has a lot of fun and powerful cards with a lot of interesting combos and interactions to discover.
