Whenever Infectious Ego enters or attacks, exile the top card of target opponent's library. If it's a land card, that player gets a poison counter. You may play that card for as long as it remains exiled, and you may spend mana as though it were mana of any color to cast that spell.

As Nebula of Empty Gold enters, choose two or more colors. You lose life equal to the number of colors chosen this way.
{T}: Add one mana of any of the chosen colors.

Draw a card, then draw cards equal to the number of cards named Sea Cache in your graveyard.

When Terraformer's Globe enters, draw a card.
{T}: Target land you control becomes the basic land type of your choice until end of turn.

This spell costs {2} less to cast if your starting deck contained at least forty cards more than the minimum deck size.
When Unrivaled Fireweaver enters, you may exile a red instant or sorcery card you own from outside the game. Until the end of your next turn, you may play that card.
