Scour the Laboratory: A Powerful Tool for Delirium-Focused Decks

TL;DR Summary

Scour the Laboratory is an incredibly versatile instant that can be used to draw three cards at an effective mana cost of just one blue, provided you have four or more card types in your graveyard. This makes it an excellent removal spell for decks focused on delirium synergies.

Detailed Card Mechanics and Interactions

Scour the Laboratory is a straightforward card with a simple text box: "Delirium — This spell costs {2} less to cast if there are four or more card types among cards in your graveyard. Draw three cards." The key component of this card is its delirium trigger, which reduces its mana cost significantly under specific conditions.

When Scour the Laboratory enters the command zone, it doesn't immediately resolve; instead, its delirium trigger checks for the presence of four or more card types among cards in your graveyard. If this condition is met, the spell's mana cost is reduced by two blue mana, effectively making it a one-mana instant.

If Scour the Laboratory resolves, it draws three cards from the top of your library. This can be a game-changing effect, especially when combined with other card draw effects or delirium triggers.
