Artifacts

[Curious penguin]

Do artifacts have summoning sickness?
Like to use its ability, such as elixer of immortality.

[Keyeto]

Artifact creatures do, but regular artifacts do not, unless stated otherwise.

technically everything has summoning sickness but it only affects creatures.

[Mentonin]

Actually not, only creatures have summoning sickness. Summoning sickness means you can't attack or tap creatures without haste for triggered abilities with the {T} symbol or the "tap this creature: do something" effect if you haven't controlled them since the beggining of your upkeep. (if a card says, say, "tap five untapped Myrs you control. {Myr battlesphere} gets +x/0 and deals x damage to defending player", it doesnt count to sickness)

[scarsabrex]

yes but a {glint hawk idol} which is animated can't attack the first turn it is in play

[BlackJester]

For each creature, you can't attack with it or use its {T} abilities unless you controlled it since the beginning of your turn.

Say you cast a {Chalice of Life}. You could tap it right away if you want, but if you made it a creature with {Tezzeret, Agent of Bolas}' -1 ability, then you couldn't tap it for its ability.
