The Rules

[quote from="Lab Description" class="riot"]

A high-speed, high-variety fiesta of deeply discounted cards and fast thinking!

Something's gone very wrong with the Temporal Transducer, and the Lab looks... a little different.

This mode's even quicker than Quick Draw. Each round you get a new hand of heavily discounted cards, and 4 mana to spend on them! Think fast, choose carefully, and ask yourself: What would Urf do?

Notes:

• This game mode is very similar to the Quick Draw lab with subtle differences
• Your mana will start with 4 mana crystals and full spell mana; you crystal count won't increment like in normal matches
  • Use your spell mana wisely -- many game-changing cards like [runecard]Feel the Rush[/runecard] and [runecard]The Ruination[/runecard] only cost 3 mana!
  • If you play a card that would give you additional mana crystals (e.g., [runecard]Catalyst of Aeons[/runecard]), it will work
• You hand will be randomly-generated fleeting cards
  • You'll start the game with a mulligan of 4 cards, 2 additional cards drawn after the mulligan, and 1 copy of Prolong
  • When the round ends, you'll discard any unplayed fleeting cards (i.e., most of your hand) and draw 6 new cards
  • Prolong is a 0-mana burst speed spell which will remove Fleeting from a single card. You start the game with one copy and receive an additional copy at the start of every odd-numbered round.
• The card costs work as follows:
  • Cards that would normally cost 0-2 mana cost 0
  • Cards that would normally cost 3-4 mana cost 1
  • Cards that would normally cost 5-7 mana cost 2
  • Cards that would normally cost 8-15 mana cost 3
• Creating a exact copy of any card will reduce its cost again.
• Anything that is based around a card's mana cost like [runecard]Concurrent Timelines[/runecard] and [runecard]Ethereal Remitter[/runecard] will use the reduced cost and should be avoided

Strategy

This is a very RNG-centric lab geared towards winning quick or losing quick. Some games will simply be "low rolled" and unsalvageable. Here are a few secrets to helping you win the more competitive matches, though:

1. Try to float spell mana when you can. Many games are decided by one player "popping off" when their able to use their spell mana to play a powerful series of cards in a single round
2. Be very selective in how you use your Prolongs -- if none of your current options are great, don't be afraid to save it for a future round. Some good targets include:
   • Disruption spells like [runecard]Vengeance[/runecard], [runecard]Harsh Winds[/runecard], and [runecard]Will of Ionia[/runecard]
   • "Game Closers" like [runecard]The Harrowing[/runecard], [runecard]Aurelion Sol[/runecard], and big celestials
   • Board clears like [runecard]The Skies Descend[/runecard], [runecard]The Ruination[/runecard], and [runecard]She Who Wanders[/runecard]
3. [runecard]Warmother's Call[/runecard] and [runecard]Feel the Rush[/runecard] are extremely powerful in this game mode and almost always worth playing
