Pick up to 4 Yu-Gi-Oh! cards of the same kind to compare stats, types and effects. The first card you pick sets the kind of card being compared.
How do we keep it fair?
Monsters have ATK/DEF, while Spells and Traps only have effects and activate at different times, so each kind is only compared with its own kind.
Kinds that can be compared: Monster, Spell, Trap.
