Manticore Spa

{t}: Add {c}.
{t}: Add one mana of any color. Use this mana
only to cast manticore spells. If a manticore spell
is cast with this mana, it gains haste until end of
turn.
Whenever a manticore you control becomes
tapped, you can choose to exile it. You can
choose to return it to the battlefield untapped
under your control at the start of your next
beginning or end phase (your choice).
