This is what I really enjoy about Doubles - there are so many moves with 0 value in Singles that can turn the tables in Doubles. Who would have thought of using Imprison in Singles? This move can be so gamebreaking, preventing the opponent from using common moves like Protect, Trick Room, Earthquake, etc, disrupting the opponent's plans while making your mission easier to execute.
Skill Swap, a move with no use in Singles, but a rad move in doubles, as elaborately explained by Level 51 and Darkmalice! Technician Mr. Mime in particular is an interesting Skill Swapper - Technician Mamoswine with Ice Shard / Icicle Spear anyone?!?! I had no clue Teeter Dance confused multiple users, either xd.
Bulky Skill Swappers are more consistent, imo. Darkmalice described how Cresselia can skill-swap its Levitate to Heatran, which is fucking cool. Also re-activating Intimidate with Skill Swap and
weather are also interesting uses of this ability. NixHex has showed one of his VGC logs where he skill-swapped Ninetales's Drought to his Cresselia, who immediately summoned the sun back up! If the opponent changes the weather, Cresseli can simply skill swap Drought to the opponent or his partner to bring back Sun! NixHex was able to keep Sun up through out the game despite Ninetales getting knocked out earlier in the game!
And lol, Ally Switch! Imagine the opponent's frustration as Beheeyem and its partner switched positions xD Beheeyem's partner avoids a potentially lethal attack while staying on the offensive. The move has +1 priority so being slow is okay. Ally Switch is somewhat similar to Rage Powder / Follow Me in that it causes the opponent's moves to miss its target ;d.
Finally, Bummer has graciously blessed us with his manly logo skills! Check it out!
Victini riding a Cresselia~ two brawny intimidate users and Shaymin-Sky's head crest carved into the logo! Ty, Bummer for this amazing artwork!!! Bummer's logo is on the Leaderboard post, which I am working hard to update x0 Still in progress, so please be patient!
EDIT: ty, OVERGRO for catching my mistake, I'll fix this.
