Isxix, The Arachnagon

Flying, webtouch (Tap creatures damaged this way,
they don't untap on their next untap phase)
As long as you control Isxix, other creatures with flying and/or haste lose them. They gain defender.
At the beginning of each endstep, you may pay {b/g}{b/g}. If you do, put a -1/-1 counter on each
creature with defender.
