Thanks! Timeshift is basically "infect that wins going 0-1" and appears in blue and black. The 15 seconds would have to be balanced through playtesting.

New challenge: Legacy of the Planeswalkers.

Next year's summer supplemental set has been announced! It's a set built around the impact of planeswalkers on the planes they visit, from the present to the distant future. This impact comes in many forms: Laws enacted, stories told, sites of great deeds, even descendants scattered through the planes (sparks are not hereditary). The set can be drafted and is legal in Vintage, Legacy, and Commander.
