Dude.. im dealing with the same exact thing.. im about to play my bro who brings teclis in an almost deathstar phoenix guard.. i was planning on taking slann lore of death and sniping him (especially with bane head) or dwellers below with his S2.. buuut.. he pointed out the banner of the world dragon which means slann is useless
but then i was thinking.. i could easily kill him in close combat with simple saurus. with the new step up rules where everyone still attacks back then if Saurus still have a few ranks your looking at around 9 attacks against WS3 T2 no save Teclis, just dont declare a challenge so he wont go to the back ranks..
Now the only problem with this is actually getting into close combat with high elf magic and shooting.. not a huuuge deal tho.. Sun Standard on BSB and get MR in there however.. the initative test spells will slaughter tho but thats why you bring two or three units annnnnd...
Slann with Lore of Light making then I10 WS10.. with Phas Protection thats an extra -1 Hit modifier.. also with slann... bring feedback scroll with bane head.. when he throws those 5 or 6 dice then BAM.. i just rolled two 5s.. what? THE Teclis doesnt have Ward save?.. well then hes dead my friend.. 65 pt wizard killer.. (MR doesnt work with Feedback scroll does it?)
Oxyotl is another choice but very risky... theres a few more things i thought off but if he brings Banner of World DRagon than Saurs are next best.. bu if he doesnt, then Sniper Lore of Death or Dwellers Below..
Any thoughts anybody cause im still afraid to play my bro in a few days haha
