{U}, Sacrifice Aether Spellbomb: Return target creature to its owner's hand.

{1}, Sacrifice Aether Spellbomb: Draw a card.

When Bladecoil Serpent enters the battlefield, for each {B}{B} spent to cast it, each opponent discards a card.

When Bladecoil Serpent enters the battlefield, for each {R}{R} spent to cast it, it gets +1/+0 and gains trample and haste until end of turn.

Counter target spell.

Flying

Other artifact creatures you control have flying.

When Cyberdrive Awakener enters the battlefield, until end of turn, each noncreature artifact you control becomes an artifact creature with base power and toughness 4/4.

At the beginning of combat on your turn, populate. The token created this way gains haste. Sacrifice it at the beginning of the next end step. (To populate, create a token that's a copy of a creature token you control.)

Search your library for an artifact card, reveal it, put it into your hand, then shuffle.

{T}: Choose target artifact a player controls and target artifact card in that player's graveyard. If both targets are still legal as this ability resolves, that player simultaneously sacrifices the artifact and returns the artifact card to the battlefield.

Enchant artifact

When Mightstone's Animation enters the battlefield, draw a card.

Enchanted artifact is a creature with base power and toughness 4/4 in addition to its other types.

{2}: Mirage Mirror becomes a copy of target artifact, creature, enchantment, or land until end of turn.

{R}, Sacrifice Pyrite Spellbomb: It deals 2 damage to any target.

{1}, Sacrifice Pyrite Spellbomb: Draw a card.

Flying, vigilance, trample, lifelink

{5}, Exile Scavenged Brawler from your graveyard: Choose target creature. Put four +1/+1 counters, a flying counter, a vigilance counter, a trample counter, and a lifelink counter on that creature. Activate only as a sorcery.

{1}, {T}, Sacrifice another artifact: Reveal the top eight cards of your library. Put up to two noncreature artifact cards with total mana value less than or equal to the sacrificed artifact's mana value from among them onto the battlefield and the rest on the bottom of your library in a random order.

Draw three cards. Then discard two cards unless you discard an artifact card.

Trample

Traxos, Scourge of Kroog enters the battlefield tapped and doesn't untap during your untap step.

Whenever you cast a historic spell, untap Traxos. (Artifacts, legendaries, and Sagas are historic.)

Read ahead (Choose a chapter and start with that many lore counters. Add one after your draw step. Skipped chapters don't trigger. Sacrifice after III.)

I -- Create a 0/2 colorless Thopter artifact creature token with flying named Ornithopter.

II -- Tap any number of untapped artifacts you control. When you do, Yotia Declares War deals that much damage to target creature or planeswalker.

III -- Up to one target artifact you control becomes an artifact creature with base power and toughness 4/4 until end of turn.
