Jacob, AkShellerating Mentor

Split second. Creatures you control have Haste.
When Jacob, AkShellerating Mentor enters the battlefield, Target creature gains haste until end
of turn.
When Jacob, AkShellerating Mentor attacks,
spells you control cost {x} less to cast,
where X is the number of attacking creatures.
As was once said "To suffer the penalty of too much
haste, which is too little speed.", which means we
should be going faster!
