Elius, Sage of Boons

If a creature you control would get +X/+X until
end of turn, where X is greater than 0, put that
many +1/+1 counters on it instead.
If a creature you control would gain flying until
end of turn, put a flying counter on it instead.
The same is true for first strike, double strike, deathtouch, lifelink, menance, reach, trample,
and vigilance.
