•Lead Tentacruel is decent, its whole premise is outspeeding and threatening big damage on leads such as Dragonite, with Wrap to pivot out of bad MUs, although it tends to be very hit or miss, as if it misses your entire team can fall apart if if Tentacruel gets paralyzed or the like, though that Tentacruel set is completely unusable, as A) Tentacruel isnt getting any free turns at all to set up Reflect, and B) it lacks Rest, which means if you take any damage or paralysis whatsoever, it is permanent. You need to replace Reflect with Rest on Tentacruel to make this work.
•Once again with the Relfect shenanigans, Reflect on Kadabra is also completely unviable, as one crit from really any physical attack can spell the end of it, it doesnt get any free turns to set Reflect up, and it can still be paralyzed by Body Slam from the likes of Dewgong. Omastar, Vaporeon, etc. Only having 1 attacking move can also prove to be detrimental for you if you run out of PP. I recommend you replace Psychic with Seismic Toss to have much more PP to attack with, and for consistent damage.
•Rock Slide on Kangaskan is usable, but its outclassed by Counter as a better 4th move option, as it can let you deal back double the damage to opposing Kangaskan, Dodrio and Persians STAB Normal type attacks. Articuno isnt ever going to be switching in on you, and in a 1vs1 Rock Slide wont OHKO it without a crit, Body Slam can also paralyze the opposing Articuno, which lets you outspeed it and gives you another free turn to attack it before your KOed.
•Like always, Vaporeon is sitting here wondering why its not a Dewgong, yes it has Acid Armour, but it hits less hard than Dewgong due to a lack of STAB Blizzard, and it can also potentially be frozen by Articuno's Blizzard, while Dewgong cant be frozen. This Vaporeon also struggles greaty vs Tentacruel, Dewgong, and other Vaporeon due to it lacking Body Slam to paralyze them and hit them for neutral damage, I recommend you replace Vaporeon with a Dewgong to better wall and hit harder with STAB Blizzard, as without it, this team melts to Articuno.
•Dugtrio is not staying in on a Tangela, so you are not going to get the opportunity to paralyze it with Stun Spore, Mega Drain is also not going to keep you on the field for longer. As the health recovery is minimal. This Tangela also lacks Bind, which means it cant pivot out of bad matchups. The main way to take down Dugtrio also isnt to paralyze it, its to take advantage of its frailty and lack of recovery and try to KO it by battering it with attacks. Growth is not going to work well as you will need to switch out infront of Tentacruel, who takes next to nothing from Mega Drain, chokes you with Wrap, and has Blizzard, or anything else that has coverage or STAB Blizzard. Stun Spore can also miss, while TWave cant. I recommend you replace Tangela with Dragonite, who is faster, has TWave over Stun Spore, the higher accuracy Wrap, and Blizzard to 2HKO Dugtrio, while Tangela's STAB Mega Drain is a pitiful 3HKO on Dugtrio.
