The time as come for me to choose a winner for this round and if you're not dont think i dont like your cards but i choose the one who respect the most criteria and the other ability fit with trample like its twin brother and for this Exmortis got a real example of how a Behemoth can crushe everything on its path and stomp on enemies more and more until everything is chaos and waste are the winner, for the other keep reading im giving you my tough.
Chaoscal: your goblin where just plain cruel (i like to destroy land) and realy felt like if he was blocked he explode and deal its trample damage and make the place explode your card is one of my favorite (theres not too much card but i mean it)
E.S marcus: nice one but some mistake need to be fixed dont put basic creature that doesn't exist and put assasin with humain to fit more the lore of your card and i dont think bleed fit with poison counter but i you fix these little things this card would be one of my top favorite
Commander: what a weird creation But a good creation the only thing is some wording problem you can't put +1/+1 counter on non creature card you should replace it like (example Petal counter(that a bad example but its still is)) and then make is last activate effect read as claretthirst garden become a X/X with trample until the end of the turn where X is the number of petal counter on it. i would prob be first if your card meet the requirement 2 mana cost minimum. but like i said earlier your cards is much more than interesting.
Giniosuke: Your card was ok but i don't know why i don't realy feel that the transformed version is a big NIGHMARE OF DOOM like i said picture that you chose are realy important to me the first one is perfect the other is meh for the effect it would have been GIGAGREAT if the picture matched.
Overall gj all ill make a new one tomorow this one will work differently!
