"Gearfried the Iron Knight's" effect is a Continuous Effect. If a monster attacks "Gearfried the Iron Knight", and you activate "Blast with Chain" during the Damage Step, "Blast with Chain" is destroyed and gets its effect, so you can destroy the attacking monster before Damage Calculation. If you select your opponent's "Gearfried the Iron Knight" with "Snatch Steal", "Snatch Steal" is destroyed when it resolves and "Gearfried the Iron Knight" remains on your opponent's side of the field. |
