Chron, Blind Eternities Guide

{2}{c}: Until your next turn, if a player would begin an extra turn, that player skips that turn instead, Scry 1.
If Chron of the blind Eternities is your commander, each nonland card in your deck may have up to 3 other cards that have the same name. Your deck cannot contain an eldrazi card.
Thank you for fixing my grave mistake, Gatewatch.
