You can activate Wicked Wolf's last ability even if it's already tapped
Control Option 6-cost Sakazuki is a control Character, allowing you to KO one of the opponents 5-cost or less Characters if you have 2 rested Characters in play
RRR+ Double Blaze-GX 200+ If this Pokmon has at least 3 extra [R] Energy attached to it (in addition to this attack's cost), this attack does 100 more damage, and this attack's damage isn't affected by any effects on your opponent's Active Pokmon
Even the occasional more aggressive deck might choose to sideboard it in the right metagame
Again exceptions exist, one being Chandra's Ignition, where for a bit more of a set up cost, the damage dealt can be huge without breaking your mana bank or your regular bank for that matter
I do love a good way to draw extra cards each turn when Im playing blue, and Wiretapping is a good one
