Yes, as long as it’s not a creature. Only creatures are affected by summoning sickness. If March of the Machines was in play or Ratchet Bomb became a creature by other means, you wouldn’t be able to tap it if it came under your control that turn. Otherwise, it can tap immediately.
Can you tap a creature on the first turn?
Creatures. Creatures represent people or beasts that are summoned to the battlefield to attack opposing creatures or players and defend their controller from the attacks of enemy creatures. They normally cannot attack or use an ability with the “tap symbol” on the first turn they enter the battlefield.
Can you tap a creature on the turn it enters play?
Ignore this rule for creatures with haste A creature that has the Haste ability can tap immediately, so unless you have a Reflex Sliver on the ‘field, you will not be able to tap a Gemhide Sliver for mana on the turn it comes out. There is a comprehensive rule citation, but basic questions should also have basic references.
When can I tap a creature with summoning sickness?
If [this] refers to the card that’s been under control since the beginning of your turn, you can use it this turn along with the “tap an untapped creature” this turn because this part doesn’t use the tap symbol. The summoning sickness only applies to activating the tap ability, which is different cost from “tap an untapped” creature.
Can a creature ability be played as an instant?
Now I get only more confused when I read my own post, but hopefully someone understands 😀 Creature abilities can be played as instants, so you can use them on your opponent’s turn. A creature that you play has summoning sickness until your next turn, so if the ability has a tap symbol in it, you can’t use it until the turn after you play it.
What happens when a creature enters the battlefield?
Unlike other types of permanents, creatures enter the battlefield with “summoning sickness”: a creature can’t attack, or use an ability that has {T} in its cost, until it has started your turn on the battlefield under your control. You can block with a creature or activate its other abilities no matter how long it’s been on the battlefield.
