Edos now can be restrained by drowning them in yomi numa and they would be unable to move to take out explosive tags
Tobirama couldnt do anything when he couldnt move against madara
Fighting with marked kunai isnt Tobirama's style, never used kunais in flashback or even in juubi fight
Even the mark was present on the blade not on the handle, seems he got the idea after seeing Minato's kunais and tried to use a hastly marked kunai
Anyway even if he does it thrown kunais can be deflected mid-way with Hair needle barrage and i dont think kunais or swords would damage jiraiya with the durability he gains in sage mode
So yes the match does seem to be going towards a draw unless Jiraiya somehow destroys every mark Tobirama has, there wont be many since he has to manually put them, and corners him
