Idris, Hawthorn Vagabond

At the beginning of your upkeep, put a season
counter on Idris, Hawthorn Vagabond. Then, if
there are four or more season counters on it,
remove all season counters from Idris, and it
gains defender until end of turn.
{t}: Add one mana of any colour. Search your
library for a basic land card, put it onto the battlefield tapped, then shuffle your library.
Activate this ability only if Idris has exactly two
season counters on it.
