People don't understand trample+deathtouch

I am still quite new, having only played some weeks. I am now on platinum 4 Alchemy with my own deck, mainly due to [[basilisk collar]] on a big boy with trample. Oh, you are blocking my 14 power beast with a combined toughness of 9 divided over three? Shame that I will only deal them one each before delivering the rest to you.

Why does it seem like no-one else is doing this? Will I get wiped at higher rank?
