{T}: Add {C}.
{T}: Add one mana of any color. Spend this mana only to cast a Sliver spell.
{5}, {T}: Create a 1/1 colorless Sliver creature token. Activate only if you control a Sliver.
Whether you control a Sliver is checked only when you activate the last ability, not as that ability resolves. If you control no Slivers at the time the ability resolves, you’ll still get a Sliver token.
