After destroying a second monster, “Great Dezard” still retains his first effect.
If your opponent uses “Double Snare” against “Great Dezard” after “Great Dezard” has achieved his first effect, “Double Snare” is negated and destroyed.
If “Great Dezard” is removed from the field after activating his first effect and then returns to the field, he loses his previously-achieved effect(s).
You can Special Summon only 1 “Fushioh Richie” by Tributing “Great Dezard”.
“Great Dezard” can achieve his effects by destroying Monster Tokens.
