Quote from user_938036 »I'm going to assume you mean successful rather than successive. The first flip gives +3/+3, the second +6/+6, the third +12/+12, the fourth +24/+24, the fifth +48/+48. With his power set down to 1/1 rather than the normal 3/3 he will be 94/94. When something "doubles" its power or toughness it literally means "it gets +X/+X where X is its power or toughness" Setting somethings power and toughness doesn't remove additional buffs only the initial value.
