What is this? It's an embedded graph with clickable points. Since I made a table for speeds, I had all the values, I added the base speed to each value as a second coordinate to visualize in 2d, meaning each value will be on the same height based on it's base value. Using two speed down on any opponent axie, even a 61 speed bird slows it down to 36 or under, and since those cards are reptile or bug, you wouldn't really need speed down on 36 speed, so kind of irrelevant, if you speed anything down twice, it will go after your midlaners, maybe before your tank. Speedups are relevant, as they got no cap upward and they can go to 5, like goldfish is hit 5 times or 2 goldfish hit 3 times, they cap out on 5 maximum speedups, for speed downs you would need to hit 5 times for minus 5 but 2 will make that axie last or go before your tank. So the 2nd line, the straight one is the base speed going from 31 to 61. Each line to left is the speedups, the first line is the speed down values.
So the second is the base speed, and the others are +1 +2 +3 +4 +5 speedups As you can see the first 5 slowdown dots are parallel to the original speed, but the 6th has more effect on it, the more the speed is the more the speedowns and speedups become more effective. It's due to the 20% and the round downs I used, if the fractional values are in use, then it would be a completely straight line each time, so this way it's a bit of rounding error, I'm still not sure if 61.1 would be faster than 61, so that is my reasoning behind this. And I got no way to check. But for reference: everything is round down to lower value, so it's at least that speed or more.
So if you look at the X coordinate, a line on 61 would mean the bird speed, (62,52) is right to it so it means any value above 52 will be faster than a bird on base speed. Same for the aqua, (58,49) means any value above 49 with one speedup is faster than an aqua on 57. The 4th line (58,42) means any value at or above 42 and 2 speedups is faster than the aqua on 57. And lastly (63,45) means any value at or above 45 with 2 speedups, would be faster than a bird on 61. The first line is the speed down. 1 speed down with 48 speed makes birds slower than 48. Add one for measure, as your hp might be higher than him so on same speed you go second. So 49 speed 1 speed down to be faster than birds (2 downs 36 if you wonder), (45,57) means one slowdown for 57 speed aqua brings it down to 45(two speed downs 34), so you need to be at least 46 speed fast to go faster than a full speed aqua.
