Lotus Ring

This land enters tapped. As it enters, choose a color. T: Add one mana of the chosen color. 1, T: For each color among monocolored permanents you control, add one mana of that color.

Create a token that's a copy of target artifact or creature you control, except it's an artifact in addition to its other types. It gains haste until end of turn. Sacrifice it at the beginning of the next end step.

When this creature enters, create a 3/3 colorless Golem artifact creature token. 2, T: Put a +1/+1 counter on each creature token you control. They gain trample until end of turn.

Menace When this creature enters, other creatures get -2/-2 until end of turn. 1B, Discard this card: Target creature gets -2/-2 until end of turn.

Menace At the beginning of your upkeep, you may create a Treasure token. When you do, target opponent creates a tapped Treasure token. Whenever this creature attacks, it deals damage to defending player equal to the number of artifacts they control.

Trample Whenever this creature or another creature you control with power 4 or greater enters, you gain 3 life and draw a card. When this creature dies, if it's not a token, create a token that's a copy of it, except it's an artifact in addition to its other types.

If you would create one or more artifact tokens, instead create those tokens plus an additional Map token. (It's an artifact with "1, T, Sacrifice this token: Target creature you control explores. Activate only as a sorcery.") 1U, T: Create a token that's a copy of target artifact token you control.

When this enchantment enters, search your library for up to five land cards that have different names, exile them, then shuffle. At the beginning of your end step, choose a card at random exiled with this enchantment and put it onto the battlefield tapped.
