Toothless, Draconic Alpha

Flash, Flying
Dragons you control can't be blocked by
creatures with reach
If this creature entered the battlefield on
your turn, it gains Hexproof
If this creature entered the battlefield on an
opponent's turn, it gains haste until end of turn
Whenever a dragon you control attacks or blocks,
put x +1/+1 counters on it, where x is the
number of dragons you control, until end of turn
