Borrin of Stonehall

Dwarves you control have menace.
When Borrin attacks, for each creature controlled by the defending player, put a +1/+1 counter on Borrin. Remove all of these counters
at the beginning of your next upkeep.
{1}{r}{r}: You may cast your next Dwarf spell without paying its mana cost until end of turn. If it is a creature, it gains haste.
