貪る光 {1}{W}{W}

Notes and Rules Information for 貪る光:

• Only the English version of a Magic card receives Oracle updates and errata. View this card in English. (Scryfall note)
• You can tap untapped attacking or blocking creatures you control to help cast Devouring Light. This doesn't remove those creatures from combat. (2014-07-18)
• The declare blockers step is the last chance to cast Devouring Light before creatures deal their combat damage. However, a creature remains an attacking or blocking creature during the combat damage step and end of combat step. Devouring Light may be cast targeting such a creature during those steps, after the creature has dealt combat damage. (2014-07-18)
• You can tap any untapped creature you control to convoke a spell, even one you haven't controlled continuously since the beginning of your most recent turn. (2021-03-19)

• When calculating a spell's total cost, include any alternative costs, additional costs, or anything else that increases or reduces the cost to cast the spell. Convoke applies after the total cost is calculated. Convoke doesn't change a spell's mana cost or mana value. (2021-03-19)
• If a creature you control has a mana ability with {T} in the cost, activating that ability while casting a spell with convoke will result in the creature being tapped before you pay the spell's costs. You won't be able to tap it again for convoke. Similarly, if you sacrifice a creature to activate a mana ability while casting a spell with convoke, that creature won't be on the battlefield when you pay the spell's costs, so you won't be able to tap it for convoke.
