Stage 103 Valk has 224 SPD. The actual math around whether she'll cut in is *very* complex, and one which if you truly want to get the exact number, you'd be best off using Excel to plot it all out. You'd need to start with the base tick formula, figure out who is going first, get the TM count on all the champs after they act, and then reduce the TM count on each champ who receives a buff by 10% for each buff they receive, and increase the tick count on Valk by 10% for each buff placed.
As an example of the first step in this chain, suppose you had Lydia lead with her A2, which places two buffs on each of your five champs, and suppose you had Lydia with 300 SPD and Seer with 270 SPD (and everyone else slower, for this example):
Lydia TM per Tick: 300 * 0.07 = 21
Seer TM per Tick: 270 * 0.07 = 18.9
Valk TM per Tick: 224 * 0.07 = 15.68
100/21 = 4.76 --> 5 ticks to reach full TM
Seer TM after 5 ticks = 94.5
Valk TM after 5 ticks: 78.4
Seer TM after two buffs placed by Lydia: 87.5*0.9*0.9 = 76.545
Valk TM after two buffs placed by Lydia: 78.4*1.1*1.1 = 94.38
Seer new TM per Tick after SPD Up = 24.57
Seer TM after 6 ticks = 101.115
Valk TM after 6 ticks = 110.06
And so, even with that very basic example, you can see how complex it gets - and just how much speed you'd need to have if you wanted to run someone with buffs to enable Seer. Probably a better avenue would be to have someone with CC to control the Valk, so that you can let them cut ahead and lose their turn.
