Extreme Force Card List and Set Guide

Overview

Extreme Force released February 1, 2018, with 100 cards under the EXFO set code: 44 Commons, 4 Short Prints, 20 Rares, 14 Super Rares, 10 Ultra Rares and 8 Secret Rares.

98 of the 100 cards were new to the TCG. The other two have an earlier 2017 printing in the catalog.

Mekk-Knight gets twelve cards, monsters that Special Summon themselves into a column holding 2 or more cards. Tindangle gets nine Flip monsters and support cards, Mythical Beast six Pendulum Spellcasters that collect Spell Counters, and Rokket four more cards.

Cards and rarities

Extreme Force has 100 set codes, each starting EXFO-EN and printed under the artwork on the right. Where a card comes at more than one rarity, every version shares its code, so the table counts set codes at each rarity and a code printed at two rarities is counted twice.

Each set code has one rarity, so the 100 set codes are also 100 printings. Set completion in TurnZero HQ counts the distinct set codes you own against the set's total, so a card printed at two rarities counts once, with an every-rarity count beside it for collectors chasing each version.
