Tishana's Tidebinder not working as the rules text implies
Having quickly read down this list I see there are multiple other concerns with Tishana's Tidebinder not working correctly. I have recently played with it against the Ouoroboroid/Sazh's Chocobo/Managorge Hydra deck and have used it against all three of those creatures and the 2/1 mythic from FF which doubles its power on a landfall.
Sometimes Tidebinder works correctly and prevents the abilities from triggering for the rest of the game, but other times it does not - i.e. it counters the ability once but then the next turn the landfall triggers are happening again.
The only thing that potentially seems to increase the likelihood of this happening is when the creature with the ability being countered gets modified (i.e. becomes enchanted or gains a +1/+1 counter) - though that rule of thumb doesn't seem infallible as I did counter a sazh's chocobo ability and then the next turn it was triggering again without being modified.
I've lost multiple games because of this at this point and it actively makes tidebinder a significantly different card - would appreciate it being fixed! Thank you!
