Spelltrapper Tornado

Flash
Enchant Island you control
Enchanted Island can't generate mana
When Spelltrapper Tornado enters the battlefield, counter target spell. If that spell is countered this way, exile it instead of putting it
into its owners graveyard. You may look at and
cast that spell for as long as it remains exiled,
and you may spend mana as though it were
mana of any type to cast that spell.
