Manabase tool

Deck Loader

1. Paste your decklist into the entry box. Most online deckbuilders will have an "export" or "export to Arena" feature to let you copy your decklist in the right format.

• Moxfield: More -> Export -> Copy for MTGO. Do not use "Copy for MTGA" as it will remove any cards that aren't in the Arena card pool

• Archidekt: Extras -> Export Deck -> Copy. Make sure to uncheck "Include out of deck cards" If you have a maybeboard for your deck

• TappedOut: Download / Esport / Embed Code -> Copy to Clipboard

• deckstats.net: Tools -> Decklist

• MTGGoldfish: Export to Arena

• Scryfall: Export -> Copy to Clipboard

2. Click "Load" to retrieve the cards in your deck from our database

3. Click "Compute" to analyze your deck

Color Analyzer

The color analyzer is built to test how well your deck's manabase can support its spells, and identify where it needs improvement. It does so by calculating 2 metrics:

1. Cast rate: For a spell with a mana value of X, what is the probability that you will have the mana available to cast it on turn X?

2. Average Delay: On average, how many turns do you have to wait past turn X to be able to cast a spell? (this includes cases where it can be cast immediately)

These two tend to be fairly closely related, with a lower cast rate leading to a higher cast delay. However, cast delay can account for colors that have fewer sources in your deck and take longer to topdeck

In general, a 90% cast rate or 0.3 average delay indicates that your deck has strong support from its manabase, while an 80% cast rate or 0.6 average delay is in need of improvement

This analyzer recommends improvements by calculating these values for multiple variations on your manabase: one with an extra wastes, and one for each basic land type with an extra copy of that land

The "+1 Wastes" variation is a good metric for how well your deck can support the mana values of your cards. If it's coming back with more than +1% cast rate and -0.03 average delay, your deck probably needs more lands in general

The "+1 Basic" variations act as metric for how well your deck can support the color requirements of your cards. If the "+1 Plains" variation is only slightly better than the "+1 Wastes" variation, then your deck has the support for white it needs. But if it is a much larger improvement than "+1 Wastes", then your deck might need more white sources in general

Tap Analyzer

The tap analyzer is built to test how often your lands enter untapped, and how that effects your curve out. For the lands that enter untapped under certain conditions, it calculates the likelihood of your deck meeting those conditions. It then uses this to find the overall rate at which your lands enter tapped.

The tool uses this rate to simulate the opening turns with your deck and score how well it can cast its spells. It then runs this test again for two different versions of your deck: One with one less tap land, and one with zero tap lands. Based on the difference between the results of these two tests and the first one, it calculates the impact of tap lands on your early game.
