The TT is lava.
In your first scenario, AoE will do nothing to TT and Zealous will do ~half health at best. Timestrike All when only one mon at 200+ TU does garbage damage. Galv has HG, so if you stun Kong I stun your Galv so he can’t move after. So my TT is still alive, Galv is HG because Virid AoE doesn’t HG it in one shot, Kong may or may not be dead (Grass AoE and only single200 TU Timestrike All) but now your Galv is at 200-300 TU, and my chrono dies. My 5th and 6th are GF and any sweeper, respectively. It is now my move with Galv, GF, TT and if you unfortunately killed Kong, my sweeper moves as well. You could choose to fast strike my TT or chronox instead, but that means I either get a free kill on your chrono or get to use TT.
In your second scenario, that leaves you with only Galv and Chrono to challenge my TT and galv and Kong. Your only option is to stun Kong so I don’t throw your chrono, where I now get to stun your galv. You fast strike my TT. At this point, my Sweeper and GF come in again and your Galv/Viri/Gaia are all high TU while 3 of my mons now get to move. Your chrono instantly dies from AT + 2xProtector killer (as I’ve used that exact three moves to kill Chronozar before) because stunpulse+PK = 101 TU, while Chrono is 25-30 TU behind Galv + Faststrike = 109-114 TU. Thus I get to kill Chrono before he moves again, crave is charged. If something fast doesn’t come in, I suicide bloodcrave your Viri to HG to bring in my 7th. TU passes and now GF is around 150 TU, your Galv and Viri are both still 80 TU+ each, and you have a random monster of your choice in next slot. Gaia *may* be able to move (~40TU) if I don’t kill it with my 1st brought-in sweeper who is now at 0 TU. Brought-in support due to Galv is usually Stun immune GT, who will enter in and go to about 60 TU when my sweeper gets to move. Kong will move before Viri and has about same TU as Galv, so if you don’t kill him soon, another one of your sweepers will die. If Kong moves before Galv, skip GTer to after Galv, else GT to Kong. Zealous Viridiz, eat stun revenge. Your galvs turn at full HP. Only killable target is Kong, but that will stun you.
You’ve lost Viri, Chrono and Gaia, while Galv can’t do anything. The result of this is you lose some of the biggest sweepers from In-game monsters gameplay and I continue to sweep with my ordinary team. It just isn’t possible for the in game monsters to create a team to be PvP competitive. They lack firepower and support to carry the team through if the few big power lines that can be made are broken.
F2P wouldn’t work if it had that strict of a requirement. AI is much dumber and trickable than humans. You can beat the offline story Chapter 5 with in-game monsters, but even Hidan could barely do it. Against a similarly leg and SE stacked team, controlled by a human but lacking buffs, I doubt it’s possible to do better. You’d stand a better chance using the in-games to stun the team into oblivion and setup penguini, but sadly that doesn’t work in top PvP because we are all Front Lining stun immune.
Additionally, anyone who is running double Kami/shadow frontline says bye to chrono, as two uncharged bloodthirsts will do ~3k damage to him. If there are no timestrikers, then 2 AoEs from them will also do the trick, as well as HG or killing any non-tank/non-leg.
