Goblin Trenches requires quite the investment of mana and lands but you only need to activate it a couple of times before youve overwhelmed your opponent, especially if you throw in some goblin synergies or cards like Hellrider
For example, Cursed Eldland has an effect that allows you to add an "Eldich" or "Golden Land" card to your hand, meaning you can get any card with these words in their name into your hand, like Eldlich the Golden Lord, Golden Land Forever

You can also use monsters your opponent controls to complete an Extra Link - if your opponent has 3 co-linked monsters in a row in their Main Monster Zones, summoning 2 Links to the Extra Monster Zones co-linked to those 3 will allow you to complete the Extra Link
Instead, control decks typically get their edge through card advantage
