Simultaneous Equation Cannon Chart
This chart maps out ways to resolve the card Simultaneous Equation Cannons (SEC) for its full effect. The effect states:
Banish 1 Fusion Monster and 2 Xyz Monsters with the same Rank from your Extra Deck, whose combined Level and Ranks equal the total number of cards in both players' hands and on the field, then you
can apply this effect.
● Return 2 of your banished monsters to the Extra Deck (1 Xyz and 1 Fusion) whose combined Level and Rank equal the Level or Rank of 1 face-up monster your opponent controls, then banish all cards they control.
● Return 2 of your banished monsters to the Extra Deck (1 Xyz and 1 Fusion) whose combined Level and Rank equal the Level or Rank of 1 face-up monster your opponent controls, then banish all cards they control.
You can see every scenario in which SEC can be resolved for the full effect, if you input a ydk/ydke (or manually select levels and ranks) you can check which specific scenarios apply to your deck.
As using the chart during a tournament is against the rules, please learn how to solve it yourself quickly, this chart merely serves as a help for beginners to understand it, as well as a deck building tool. To resolve this card just think: The level/rank of an opponents monster has to be X lower than cards in play, where X is the Rank of one of my XYZ.
