At the beginning of your upkeep, create a 1/1 colorless Construct artifact creature token. If you control six or more artifacts, create a 6/6 colorless Golem artifact creature token instead. Tokens created this way attack this turn if able.

{U}, Put a travel counter on Endless Discoveries: Draw a card. This ability costs {1} more to activate for each travel counter on Endless Discoveries.

As Enlightened Sigil enters, choose a card type.
Spells you cast of the chosen type cost {1} less to cast.

Once each turn, when you activate an ability of a permanent you control that isn't a mana ability, you may exile that permanent. If you do, return that card to the battlefield under its owner's control at the beginning of the next end step.

Recruit. (Create a 0/0 white Soldier Army creature token, then put a +1/+1 counter on each Army you control.)

Enchant opponent
At the beginning of enchanted player's upkeep, they choose one that hasn't been chosen yet —
• They discard three cards.
• They sacrifice three nonland permanents.
• You transform Enrapturing Grudge.
If Enrapturing Grudge would be put into a graveyard from anywhere, exile it instead.

Landfall — Whenever a land you control enters, create an Idol token. (It's an artifact with “{1}, Sacrifice this artifact: Put a +1/+1 counter on target creature. Activate only as a sorcery.”)

Each player shuffles their hand and graveyard into their library. Then each player draws seven cards. If you didn't control a blue legendary creature or planeswalker as you cast this spell, discard three cards. Exile Entelan Erasure.

Whenever you make first contact, Entelan Idealist gets +2/+2 until end of turn. (You make first contact the first time each turn you cast a spell with a name not in your graveyard or control already.)

Menace
Whenever Entrail Elemental deals combat damage to a player, you may cast target card from your graveyard this turn. If an instant or sorcery spell cast this way would be put into your graveyard, exile it instead. (You still pay its costs. Timing rules still apply.)

Equipped creature gets +1/+0 and has poisonous 1. (Whenever it deals combat damage to a player, that player gets a poison counter.)
