Mnemonic Sphere

At the beginning of combat on your turn, create a token that's a copy of target noncreature artifact you control, except its name is Mishra's Warform and it's a 4/4 Construct artifact creature in addition to its other types. It gains haste until end of turn. Sacrifice it at the beginning of the next end step.

Affinity for artifact creatures (This spell costs 1 less to cast for each artifact creature you control.) Artifact creatures you control have menace. At the beginning of your end step, create a 0/0 colorless Construct artifact creature token with "This token gets +1/+1 for each artifact you control."

2, T: Create a token that's a copy of up to one target artifact token you control. Mill two cards. 1WUB, T, Sacrifice two artifact tokens, Exile an artifact or creature card from your graveyard: Create a token that's a copy of the exiled card, except it's an artifact in addition to its other types. Activate only as a sorcery.

Deathtouch Whenever you activate an ability of an artifact or creature that isn't a mana ability, if one or more permanents were sacrificed to activate it, you may copy that ability. You may choose new targets for the copy. (Sacrificing an artifact for mana to activate an ability doesn't count.)

As long as an artifact creature you control is attacking, prevent all damage that would be dealt to Sanwell. Whenever Sanwell becomes tapped, exile the top six cards of your library. You may cast a Vehicle or artifact creature spell from among them. Then put the rest on the bottom of your library in a random order.

This creature enters with a +1/+1 counter on it. T, Remove a counter from a permanent you control: Search your library for a Plains card and reveal it. If an opponent controls more lands than you, you may put that card onto the battlefield tapped. If you don't put the card onto the battlefield, put it into your hand. Then shuffle.

Flying This creature gets +X/+0, where X is the greatest mana value among artifacts you control. Whenever this creature deals combat damage to a player, you may reveal that many cards from the top of your library. Put an artifact card revealed this way into your hand and the rest into your graveyard.

Choose target artifact creature you control. For each creature chosen this way, create a token that's a copy of it. Overload 6U (You may cast this spell for its overload cost. If you do, change its text by replacing all instances of "target" with "each.")
